scsi: bsg: Remove support for SCSI_IOCTL_SEND_COMMAND

Browse Source 
[ Upstream commit beec64d0c9749afedf51c3c10cf52de1d9a89cc0 ]

SCSI_IOCTL_SEND_COMMAND has been deprecated longer than bsg exists and has
been warning for just as long.  More importantly it harcodes SCSI CDBs and
thus will do the wrong thing on non-SCSI bsg nodes.
