[Bart van Asche:] SCSI core never sets cmd->sc_data_direction to
DMA_BIDIRECTIONAL; scsi_bidi_cmnd(cmd) should be used instead to
test for a bidirectional command.
[Christoph Hellwig:] Bidirectional commands won't ever be queued
anyway, unless a LLD or transport driver sets QUEUE_FLAG_BIDI.
So, simply remove the respective queuecommand check in the SBP-2
transport driver.
