freedreno/a4xx: clear cached fp when switching blit prog

Browse source 
For gmem restore (mem2gmem), we swap blit programs, in order to have a
different frag shader for depth vs color restore.  But we weren't
actually clearing the cached fp, so it would not actually change the
frag shader as expected.
