Commit fadbe0cd ("staging: rtl8188eu:
Remove rtw_zmalloc(), wrapper for kzalloc()") changed all allocation
calls to be GFP_KERNEL even though the original wrapper was testing
to determine if the caller was in atomic mode. Most of the mistakes
were corrected with commit 33dc85c3
("staging: r8188eu: Fix scheduling while atomic error introduced in
commit fadbe0cd"); however, two kzalloc calls were missed as the
call only happens when the driver is shutting down.

When this driver preallocates some SKBs, kmemleak is unable to find that
allocated memory when it scans. When the driver is unloaded, that memory
is released; therefore, the report is a false positive.

There are two types of messages queued for RX. The major type, which does
I/O on the device, was being handled properly. The skbs that communicated
with the firmware were being leaked.

While rewriting the code that sets up the skb, it was possible to remove
the private variable indicating that the old skb could be reused.

_enter_pwrlock was using down_interruptible(), so the lock could be broken
by sending a signal. This could be a bug, because nothing checks the return
code here. Hence, using mutex_lock instead of the interruptible version.
Also, remove the now unused wrappers _init_pwrlock, _enter_pwrlock,
