staging: rtl8723bs: fix potential memory leak in rtw_init_drv_sw()

In rtw_init_drv_sw(), there are various init functions are called to
populate the padapter structure and some checks for their return value.
However, except for the first one error path, the other five error paths
do not properly release the previous allocated resources, which leads to
various memory leaks.

This patch fixes them and keeps the success and error separate.
Note that these changes keep the form of `rtw_init_drv_sw()` in
"drivers/staging/r8188eu/os_dep/os_intfs.c". As there is no proper device
to test with, no runtime testing was performed.

staging: rtl8723bs: Change rtw_ndev_notifier_call message to dbg

The message received in the kernel log for the state of the notifier
call doesn't seem to be of much help to end users. Changing the message
type from info to dbg to hide the message unless you are debugging
the kernel or the network subsystem.

rtl8188eu has an "android private" ioctl command multiplexer
that is not currently safe for use in compat mode because
of its triple-indirect pointer.

rtl8723bs uses a different interface on the SIOCDEVPRIVATE
command, based on the iwpriv data structure

Both also have normal unreachable iwpriv commands, and all
of the above should probably just get removed. For the
moment, just switch over to the new interface.

staging: rtl8723bs: replace DBG_871X_LEVEL logs with netdev_*()

Replace DBG_871X_LEVEL logs with netdev_*() functions
where possible (i.e. where a pointer to netdev is easily
available).

This is not possible in correspondance of redundant
log in module initialization.

So remove those ones.

DBG_871X_LEVEL macro wraps a raw printk call which is not
recommended in a device driver context, prefer using
netdev_*() log functions.

net: remove 'fallback' argument from dev->ndo_select_queue()

After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.

We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.

Tested with ixgbe and CONFIG_FCOE=m

With pktgen using queue xmit:
