Subject: [PATCH] fix:rtl8xxxu_core: mark symbols static where possible

We get 1 warning about global functions without a declaration
in the rtl8xxxu rtl8xxxu_core.c when building with W=1:
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:898:1: warning: no previous prototype for 'rtl8xxxu_gen1_h2c_cmd' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is declared
and don't need a declaration, but can be made static.
so this patch marks it 'static'.
