[PATCH] staging: r8723au: Fix build warnings

[Larry Finger]

The kbuild test robot reports the following:

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   75ff24fa52f0cc512ceee4c377632b91a3a80811
commit: 9176303c404741b2f96796466437f2badf6e289b staging: r8723au: Turn on build of new driver
date:   4 days ago
config: make ARCH=avr32 allyesconfig

All warnings:

>> drivers/staging/rtl8723au/include/rtw_mlme.h:620: warning: 'rtw_set_roaming' declared inline after being called
   drivers/staging/rtl8723au/include/rtw_mlme.h:620: warning: previous declaration of 'rtw_set_roaming' was here
>> drivers/staging/rtl8723au/include/rtw_mlme.h:621: warning: 'rtw_to_roaming' declared inline after being called
   drivers/staging/rtl8723au/include/rtw_mlme.h:621: warning: previous declaration of 'rtw_to_roaming' was here
--
   drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c: In function 'Hal_EEValueCheck':
>> drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c:2277: warning: comparison is always true due to limited range of data type

The first two warnings are fixed by making the two prototypes be "inline" to match
the actual routine. The third warning comes from testing that a u8 quantity is positive.
