Hidetoshi Shimokawa 5cdf02dbe0 Automatically detect devices that do not support READ(6)/WRITE(6)
and upgrade to using 10 byte cdbs.

As far as I tested, this works efficiently for most of the
SBP-II/Firewire devices but most of the umass devices still need
ad-hoc work around because umass-sim doesn't return any SCSI errors.

A sysctl nob is also added for the last resort.
I hope we don't need DA_Q_NO_6_BYTE quirks anymore.
