Following the recommendation of James Bottomley (of SCSI fame), this patch
changes the queuecommand() routine so that when a command is received for a
disconnected device, instead of accepting the command and then ignoring it,
we fail the command immediately with DID_NO_CONNECT.

This fixes a timeout-abort-oops sequence that would occur when the
higher-level drivers (mostly the CD driver) try to queue a SYNCHRONIZE
CACHE command during scsi_remove_host().
