From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
With the advent of per session protection flags in v3.15-rc1 code,
a target fabric driver supporting T10 PI needs to declare it's own
protection capabilities at transport_init_session() time.
This patch updates tcm_qla2xxx_check_initiator_node_acl() to extract
the T10 PI capabilities using scsi_qla_host_t->flags.difdix_supported,
and sets TARGET_PROT_ALL (all forms of PASS + INSERT + STRIP operations
supported by HW fabric offloads) when available.
