exit/rtl8723bs: Replace the macro thread_exit with a simple return 0

Every place thread_exit is called is at the end of a function started
with kthread_run. The code in kthread_run has arranged things so a
kernel thread can just return and do_exit will be called.

So just have the threads return instead of calling complete_and_exit.

staging: rtl8723bs: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This performs some refactoring to
remove needless wrapper functions, and adds a pointer back to the desired
adapter.

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.
