In commit 025d0a65 ("Use 16 bit value for plane alpha"), the alpha value was bumped to a 16bit value.
Unfortunately in drmdisplaycompositor.cpp we are still comparing it against a 8bit 0xff value, which now fails causing the display to not start.
So fix this comparing to the 16bit 0xffff value.
With this change the display starts up again.
