a646aba835 scst: Don't suspend activity during removal of a SCSI device (merge r4399 from trunk) 
SCST allows SCSI pass-through to SCSI devices registered with the SCSI
initiator core. SCST I/O activity has to be suspended before a LUN
that corresponds to such a SCSI device can be removed safely. Do not
suspend I/O when a SCSI device is being removed that has not been
exported as an SCST LUN such that removal of such devices does not
slow down I/O.
