From: Paolo Bonzini <pbonz...@redhat.com>
There is code checking s->end_transfer_func and it was not taught about
ide_transfer_cancel. We can just use ide_transfer_stop because
s->end_transfer_func is only ever called in the DRQ phase.
ide_transfer_cancel can then be removed, since it would just be
calling ide_transfer_halt.
