drm/amdkfd: Check for pdd drm file first in CRIU restore path

Browse Source 
CRIU restore ioctls are meant to be called by CRIU with no
existing drm file. There's an error path
for if the drm file unexpectedly exists. It was positioned so
it was missing a fput(drm_file).

Do that check earlier, as soon as we have the pdd.
