Gwendal Grignou 159a7ff7a1 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.
