Disable NCQ for multiport Marvell 88SX61XX SATA controllers. Simultaneous
active I/O to several disks (copying large file on ZFS) causes timeout after
just a few seconds of run. Single port 88SX6111 seems like not affected.
Skip reading transferred bytes count for these controllers. It works for
88SX6111, but 88SX6145 always returns zero there. Haven't tested others,
but better to be safe.
