drm/xe: Move survivability entirely to xe_pci

Browse source

There's an odd split between xe_pci.c and xe_device.c wrt
xe_survivability: it's initialized by xe_device, but then finalized by
xe_pci. Move it entirely to the outer layer, xe_pci, so it controls
the flow entirely.

This also allows to stop ignoring some of the errors. E.g.: if there's
an -ENOMEM, it shouldn't continue as if it survivability had been
enabled.

One change worth mentioning is that if "wait for lmem" fails, it will
also check the pcode status to decide if it should enter or not in
survivability mode, which it was not doing before. The bit from pcode
for that decision should remain the same after lmem failed
initialization, so it should be fine.
