target/loop: Enable VARLEN CDB support
Field shost->max_cmd_len is used to inform Linux / the SCSI midlayer of
the maximum CDB size an LLD is capable of handling. Set this field to
SCSI_MAX_VARLEN_CDB_SIZE for target, to enable support for
variable-sized CDBs (0x7E).
Also remove the definition of TL_SCSI_MAX_CMD_LEN since it is now
redundant.
