[PATCH 5.15.y 0/1] Manual Backport of 099606a7b2d5 to 5.15

The patch 099606a7b2d5 didn't cleanly apply to 5.15 due to the significant difference in codebases.

I've tried to manually bring it back to 5.15 via some minor conflict resolution but also invoking the newly introduced API using inverted logic as the conditional statements present in 5.15 are the opposite of those in 6.1 xen/swiotlib.
