drm/xe/vf: Fail migration recovery if fixups needed but platform not supported

The post-migration recovery needs to be fully implemented for a
specific platform in order to make continuation of workloads
possible.

New platforms introduce changes which affect the recovery procedure,
and without a clear verification of support this leads to errors
with no straight forward error message explaining the cause.

This patch fixes that issue - it introduces a message to be logged
when the current driver is known to not support the current platform.

Wedging the driver immediately also decreases the amount of
additional errors which would come afterwards if the driver continued
operation.

v2: Show the message during probe as well as during recovery; do not
  perform any recovery steps if the recovery is bound to fail
v3: Use SRIOV-specific logging, fix typos
v4: XE_DEBUG_SRIOV to XE_DEBUG check switch, to make testing more
  straightforward
