Draining PRQ is needed before repurposing a PASID. It makes sense to invoke
it in the intel_pasid_tear_down_entry().

Can you please elaborate on the value of this merge?

Draining the PRQ is necessary when PRI is enabled on the device, and a
page table is about to be removed from the PASID. This might occur in
conjunction with tearing down a PASID entry, but it seems they are two
distinct actions.
