drm/xe/vf: Post migration, repopulate ring area for pending request

The commands within ring area allocated for a request may contain
references to GGTT. These references require update after VF
migration, in order to continue any preempted LRCs, or jobs which
were emitted to the ring but not sent to GuC yet.

This change calls the emit function again for all such jobs,
as part of post-migration recovery.

v2: Moved few functions to better files
v3: Take job_list_lock
v4: Rephrased comments
