drm/xe: Dont skip TLB invalidations on VF
[ Upstream commit fd25fa90edcfd4db5bf69c11621021a7cfd11d53 ]
Skipping TLB invalidations on VF causing unrecoverable
faults. Probable reason for skipping TLB invalidations
on SRIOV could be lack of support for instruction
MI_FLUSH_DW_STORE_INDEX. Add back TLB flush with some
additional handling.
Helps in resolving,
