Matthew Auld b87482dfe8 Revert "i915: use io_mapping_map_user" 
This reverts commit b739f125e4.

We are unfortunately seeing more issues like we did in 293837b9ac
("Revert "i915: fix remap_io_sg to verify the pgprot""), except this is
now for the vm_fault_gtt path, where we are now hitting the same
BUG_ON(!pte_none(*pte)):
