[PATCH 01/11] scsi: target: Rename sbc_ops to exec_cmd_ops

[Mike Christie <michael.christie@oracle.com>]

The next patches allow us to call the block layer's pr_ops from the
backends. This will require allowing the backends to hook into the cmd
processing for SPC commands, so this renames sbc_ops to a more generic
exec_cmd_ops.
