compositor-drm: Met process stuck when do GPU PM Test

drm master was set by systemd in PM test, try to set the master back
This is a workaround patch, we should detect the EPERM error when we try to commit,

we should make sure that repaint still works from there.

Upstream-Status: Inappropriate [i.MX-specific]
