sata_qstor workaround for spurious interrupts.

The qstor hardware generates spurious interrupts from time to time when
switching in and out of packet mode.  These eventually result in the
IRQ being disabled, which kills other devices sharing this IRQ with us.

This workaround isn't perfect, but it's about the best we can do for
this hardware.  Spurious interrupts will still happen, but won't be
logged as such, and therefore won't cause the IRQ to be inadvertently
disabled.

v9fs_parse_options function uses strsep which modifies the value of the

that creates the transport potentially making the transport creation

This patch creates a copy of v9ses->option field that v9fs_parse_options
function uses instead of the original value.

"Please add a bit more detail. If DaveM is correct (he normally is), then

One or two ancient drives predated the cable spec and didn't sent the

piece of historical annoyance but a recent CD drive shows the same bug so
we have to import support for it.

Same concept as Bartlomiej's changes old IDE except that as we have
