[PATCH] gpu: gma500: psb_drv: add missing unwind goto

[Hongqi Chen]

Smatch reports that missing unwind goto in psb_driver_load().
drivers/gpu/drm/gma500/psb_drv.c:350 psb_driver_load() warn: missing
unwind goto?

psb_driver_unload() and psb_driver_load() exist in correspondence, 
and psb_driver_unload() should be executed when the psb_do_init() 
fails to initialize.
