Check if the device is powered down prior to any engine activity,
as, on such cases, all the TLBs were already invalidated, so an
explicit TLB invalidation is not needed, thus reducing the
performance regression impact due to it.

TLB invalidation is a slow operation. It should not be doing lightly, as it

Don't flush TLBs when the buffer is only used in the GGTT under full
control of the kernel, as there's no risk of concurrent access
and stale access from prefetch.

Currently, every caller performs a full barrier around a TLB

Skip all further TLB invalidations once the device is wedged and

TLB cache invalidation can happen on two different situations:
1. synchronously, at __vma_put_pages();
2. asynchronously.
On the first case, TLB cache invalidation happens inside
__vma_put_pages(). So, no need to do it later on.
However, on the second case, the pages will keep in memory
until __
