firewire: sbp2: remove redundant check for bidi command
[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. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
