Remove the goto statement from rtw_do_join(). In this function goto
can be replace by return statement. As on goto label exit, function only
return it is not performing any cleanup. Avoiding goto will improve
the function readability.

Quoted strings should not be split across lines. As put it in [1]:
"never break user-visible strings such as printk messages because that
breaks the ability to grep for them."
While at it, fix the alignment of the arguments in the sentence.
Note: this introduce a checkpatch CHECK: line length of 123 exceeds 100
columns, as the line now is:
vchiq_loud_error("%d: service %d (%c%c%c%c) version mismatch - local (%d, min %d) vs. remote (%d, min %d)",
But now the string is grep-able and the whole function call more
clear.

last_tx_time from struct sreset_priv is no longer used now that
last_tx_complete_time is gone.
This patch removes last_tx_time. This was the last remaining component of
struct sreset_priv, we can now remove the structure itself.
After removing include/rtw_sreset.h, it turned out that some definitions
in .c files were pulled in via rtw_sreset.h. Add the required include
files directly to make compilation succeed without rtw_sreset.h.

Use a Mutex instead of a binary Semaphore for the purpose of enforcing
mutual exclusive access to the "pwrctrl_priv" structure.
Mutexes are sleeping locks similar to Semaphores with a 'count' of one
(like binary Semaphores), however they have a simpler interface, more
efficient performance, and additional constraints.
There is no change in the logic of the new code; however it is more
simple because it gets rid of four unnecessary wrappers:
_init_pwrlock(), _enter_pwrlock(),_exit_pwrlock(), _rtw_down_sema().
Actually, there is a change in the state in which the code waits for
acquiring locks, because it makes it in an uninterruptible state
(instead the old code used down_interruptibe()). Interruptible
waits are neither required nor wanted in this driver.
Tested with ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano].
