[PATCH 2/2] staging: rtl8723bs: make rtw_free_xmitbuf() return void

[Hungyu Lin <dennylin0707@gmail.com>]

The return value of rtw_free_xmitbuf() is never checked. Change its
return type to void and remove the redundant _SUCCESS and _FAIL return
values. Also remove the unnecessary extern keyword from its declaration.
