[PATCH 3/3] staging: rtl8192u: remove unneeded compiler flags

[Masahiro Yamada]

-std=gnu89 is specified by the top Makefile. Adding it in a driver
Makefile is redundant.

A driver should avoid specifying the optimization flag.
-O2, -O3, or -Os is passed by the top Makefile based on the
CONFIG_CC_OPTIMIZE_FOR_* option.
