sata_mv: Prevent PIO commands to be defered too long if traffic in progress.
Use excl_link when non NCQ commands are defered, to be sure they are processed as soon as outstanding commands are completed. It prevents some commands to be defered indifinitely when using a port multiplier. Signed-off-by: Gwendal Grignou <gwendal@google.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
