ps3fb: Fix spurious mode change failures

ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it
should check the full-screen flag of the _new_ video mode instead of the
current video mode.

This bug caused spurious mode change failures when switching between
fullscreen and non-fullscreen modes using fbset, while ps3-video-mode worked
fine.
