Tweak x_hide_tip for consistency

Browse source 
* src/xfns.c (x_hide_tip, Fx_show_tip): Be consistent about using
!NILP (tip_frame) instead of FRAMEP (tip_frame).  The two
expressions are logically equivalent since tip_frame is either a
frame or nil, !NILP is a bit faster, and making things consistent
pacifies gcc 11.2.1 -Wanalyzer-null-dereference.
