bsg: deprecate BIDI support in bsg
Besides the OSD command set that never got traction, the only SCSI command using bidirectional buffers is XDWRITEREAD in the 10 and 32 byte variants, which is extremely esoteric and has been removed from the spec again as of SBC4r15. It probably doesn't make sense to keep the support code around just for that, so start deprecating the support.
