nouveau/dmem: refactor nouveau_dmem_fault_copy_one()
nouveau_dmem_fault_copy_one() is used during handling of CPU faults via
the migrate_to_ram() callback and is used to copy data from GPU to CPU
memory. It is currently specific to fault handling, however a future
patch implementing eviction of data during teardown needs similar
functionality.
Refactor out the core functionality so that it is not specific to fault
handling.
