[PATCH 2/2] staging: rtl8723bs: core: eliminate erroneous reporting of unused variable 'evt_seq'

[Zhen Lei <thunder.leizhen@huawei.com>]

GCC reports the following warning with W=1:

drivers/staging/rtl8723bs/core/rtw_mlme_ext.c:6003:15: warning:
 variable ‘evt_seq’ set but not used [-Wunused-but-set-variable]
 6030 |  u8 evt_code, evt_seq;
      |               ^~~~~~~

The local variable ‘evt_seq’ is referenced only when the macro
CHECK_EVENT_SEQ is defined, move its definition and assignment into the
control scope of macro CHECK_EVENT_SEQ, to fix the warning.

By the way, clear local coding style warnings and delete several redundant
blank lines.

Fixes: 554c0a3abf21 ("staging: Add rtl8723bs sdio wifi driver")
