Himal Prasad Ghimiray c086bfc6ff drm/xe/pm: Capture errors and handle them ...

xe_pm_init may encounter failures for various reasons, such as a failure
in initializing drmm_mutex, or when dealing with a d3cold-capable device
for vram_threshold sysfs creation and setting default threshold.
Presently, all these potential failures are disregarded.

Move d3cold.lock initialization to xe_pm_init_early and cause driver
abort if mutex initialization has failed.

For xe_pm_init failures cleanup the driver and return error code
