staging: rtl8723bs: tidy up error handling

The check for if rtw_skb_alloc() fails is done twice and is written
in a confusing way. Move the "if (!recvbuf->pskb)" right after
the allocation. The "if (recvbuf->pskb)" check can now be deleted
and the code pulled in one tab.

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.

The remove/replace operation has been done with the
following semantic patch script:

staging: rtl8723bs: remove unused code

There are two final hunks of code that are only built
if SDIO_DYNAMIC_ALLOC_MEM is defined however this is never
defined and if it was the code would lead to dereferencing
an uninitialized pointer oldmem. It appears that a previous
commit 1babeb0c3e59 ("Staging: rtl8723bs: Remove dead code")
removed some of the dead code but not all of it. Clean this
up by removing the final hunks.

staging: rtl8723bs: change semaphores to completions

This driver uses many semaphores, most of them are equivalent to
completions. The other copies of this driver got moved over to
completions a while ago, so do the same here.

In this usage scenario, the two are equivalent, so the behavior
should not change.

staging: Add rtl8723bs sdio wifi driver

The rtl8723bs is found on quite a few systems used by Linux users,
such as on Atom systems (Intel Computestick and various other
Atom based devices) and on many (budget) ARM boards such as
the CHIP.

The plan moving forward with this is for the new clean,
written from scratch, rtl8xxxu driver to eventually gain
support for sdio devices. But there is no clear timeline
for that, so lets add this driver included in staging for now.
