Subject: [PATCH 1/3] staging: rtl8188eu: core: Remove unnecessary conditionals

The variable 'pxmitbuf' is already set to NULL when entering the
function. We can remove the first conditional. When _rtw_queue_empty()
returns false, 'pxmitbuf' if not NULL. We can merge the second and
third conditional.
