This is supposed to be ->rates_ex[] instead of ->rates[].  I found this
because static checkers complain than ->rates is too small so we're
reading beyond the end of the array.  It has 12 elements instead of 15.

This bug was apparently copy and pasted from ipw2x00.  I fixed it before
in that driver 428e3cf5 ('ipw2x00: printing the wrong array in
debug code')

Rework the trace log-related lines in rtl8723au's rtw_security.c
to use the __func__ GCC magic variable instead of hardcoding the
function names into the trace log strings. This also corrects a
copy-paste-related typo in the function named rtw_tkip_decrypt23a.

Thanks to Jes Sorensen for the suggestion to use __func__.

Prior to this commit, rtl8723au's rtw_security.c had two instances of
byte array comparisons (for CRC checks) where the individual elements
of the byte arrays were compared one by one and an error trace would
be output if the byte arrays were determined to be different.

This commit improves the readability of the CRC verification by
placing the individual 4 bytes of each byte array into an 32-bit
unsigned integer and comparing the two resulting integers.

Thanks to Larry Finger for spotting the code style issues in the
previous version of this commit, and thanks to Joe Perches for
suggesting the use of 32-bit integer comparisons instead of byte
array comparisons.

Prior to this commit, functions rtw_tkip_encrypt23a and rtw_tkip_decrypt23a had
large if blocks which contained the majority of the logic in the functions.

Rework these functions so that if the negated version of the aforementioned if
blocks' conditions are true, we return from the function with _FAIL, as
expected by the calling code.

This lets us remove two levels of indentation from the functions in
question, making them more readable.
