drm/xe/vf: Start post-migration fixups with provisioning query

Browse source

During post-migration recovery, only MMIO communication to GuC is
allowed. The VF KMD needs to use that channel to ask for the new
provisioning, which includes a new GGTT range assigned to the VF.

v2: query config only instead of handshake; no need to get pm ref as
 it's now kept through whole recovery (Michal)
v3: switched names of 'err' and 'ret'  (Michal)
