Target/sbc: Set protection operation and relevant checks
SBC-3 mandates the protection checks that must be
performed in the rdprotect/wrprotect field. Use them.
According to backstore device pi_attributes and
cdb rdprotect/wrprotect field.
(Fix incorrect se_cmd->prot_type -> TARGET_PROT_NORMAL
comparision in transport_generic_new_cmd - nab)
(Fix missing break in sbc_set_prot_op_checks - DanC + Sagi)
