[kernel] Check for nullptr after gfx_create_surface_from_display

If gfx_create_surface_from_display fails to allocate memory it'll
return nullptr. If this happens we're hosed, but it's better to fail
an assert than dereference a nullptr.

Test: booted Eve w/ gfxconsole.early, then "k gfx rgb_bars"
