Subject: sata_mv: Prevent PIO commands to be defered too long if traffic in progress.

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.
