drm/xe/pxp: Fail the load if PXP fails to initialize

Browse Source 
The PXP implementation mimics the i915 approach of allowing the load
to continue even if PXP init has failed. On Xe however we're taking an
harder stance on boot error and only allowing the load to complete if
everything is working, so update the code to fail if anything goes wrong
during PXP init.

While at it, update the return code in case of PXP not supported to be 0
instead of EOPNOTSUPP, to follow the standard of functions called by
xe_device_probe where every non-zero value means failure.
