[PATCH 06/19] staging: rtl8723bs: remove all if-else empty blocks left by DBG_871X removal

[Fabio Aiuto <fabioaiuto83@gmail.com>]

remove all if-else empty {} blocks left by spatch application.

removed unused variables and an unused static function definition
after if-else blocks removal, to suppress compiler warnings.
