target: Add protection SGLs to target_submit_cmd_map_sgls

This patch adds support to target_submit_cmd_map_sgls() for
accepting 'sgl_prot' + 'sgl_prot_count' parameters for
DIF protection information.

Note the passed parameters are stored at se_cmd->t_prot_sg
and se_cmd->t_prot_nents respectively.

Also, update tcm_loop and vhost-scsi fabrics usage of
target_submit_cmd_map_sgls() to take into account the
new parameters.
