[PATCH] rtlwifi: rtl8192se: remove redundant rtl_get_bbreg call

[Peter Kosyh]

Extra rtl_get_bbreg looks like redundant reading. The read has
already been done in the "else" branch. Compile test only.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

If this code is important for the operation of the hardware, then it would
be nice to comment on it.
