[PATCH] staging: rtl8723bs: simplify NULL pointer comparisons in rtw_recv.h

[Abhai Kollara <abhai@protonmail.com>]

Fix checkpatch.pl warnings regarding explicit comparisons to NULL.
The kernel coding style prefers the shorter if (!ptr) idiom over
if (ptr == NULL). Clean up the inline functions in rtw_recv.h to
match this standard.
