The long term solution is to make grant copy use the supplied VA to copy
to/from which would mean we no longer need to pass the grant ref around
to do the copy.

This is non-trivial and would required an updated Xen.

It would also fix other use cases (such as a domU providing an iSCSI
target which is used as the block device for a local blkback).
