At present, this is probably okay.  But in the future,
as we add functionality for link power management
and hotplug polling, this could be a problem.

It becomes a problem for me certainly if we ever issue anything via
exec_internal_sg while another command may be outstanding anywhere on the
same *host*. Right now its ok.

Yeah, for serializing a pair of ATA channels on the same host chip.
