return value queuecommand should return after an unplug

[Oliver Neukum <oneukum@xxxxxxxx>]

Hi,

I am looking at the queuecommand() mathod of the UAS low
level driver. What is a host adaptor driver to do when
it gets a scsi request for an unplugged host adapter?

All teh return values I see say that something is busy.
But I have the case that something is dead and gone.

	Regards
