Rob Clark 654e9c18df drm/msm: Fix crash on dev file close 
If the device file was opened prior to fw being available (such as from
initrd before rootfs is mounted, when the initrd does not contain GPU
fw), that would cause a later crash when the dev file is closed due to
unitialized submitqueues list:
