avfilter/vf_showpalette: Don't pretend disp_palette can fail
It can't fail, yet it returns an int and other code checks whether it
failed; yet if it did fail, an AVFrame would leak. One could of course
add an av_frame_free for this (that compilers could optimize away), yet
it is easier to simply stop pretending that disp_palette could fail.
