staging: rtl8187se: Add whitespaces around '+=' and '=='

Add whitespaces around '+=' and '==' and fix coding style in these lines
as the codingStyle of the kernel recommends.

Fix checkpatch.pl errors:
ERROR: spaces required around that '+=' (ctx:VxV
ERROR: spaces required around that '==' (ctx:VxW)
