Matthew Brost 0ca229da92 drm/xe: Make LRC W/A scratch buffer usage consistent
The LRC W/A currently checks for LRC being iomem in some places, while
in others it checks if the scratch buffer is non-NULL. This
inconsistency causes issues with the VF post-migration recovery code,
which blindly passes in a scratch buffer.

This patch standardizes the check by consistently verifying whether the
LRC is iomem to determine if the scratch buffer should be used.
