This patch changes qla2xxx qlt_lport_register() code to accept
target_lport_ptr + npiv_wwpn + npiv_wwnn parameters, and updates
tcm_qla2xxx to use the new tcm_qla2xxx_lport_register_npiv_cb()
callback for invoking fc_vport_create() from configfs context
via tcm_qla2xxx_npiv_make_lport() code.
In order for this to work, the qlt_lport_register() callback is
now called without holding qla_tgt_mutex, as the fc_vport creation
process will call qlt_vport_create() -> qlt_add_target(), which
already expects to acquire it.
It enforces /sys/kernel/config/target/qla2xxx_npiv/$NPIV_WWPN
naming in the following format:
$PHYSICAL_WWPN@$NPIV_WWPN:$NPIV_WWNN
and assumes the $PHYSICAL_WWPN in question has already had been
configured for target mode in non NPIV mode.
Finally, it updates existing tcm_qla2xxx_lport_register_cb() logic
to setup the non NPIV assignments that have now been moved out of
qlt_lport_register() code.

This patch fixes a possible scsi_host reference leak in qlt_lport_register(),
when a non zero return from the passed (*callback) does not call drop the
local reference via scsi_host_put() before returning.
This currently does not effect existing tcm_qla2xxx code as the passed callback
will never fail, but fix this up regardless for future code.

This patch updates tcm_loop_driver_probe() to set protection
information using scsi_host_set_prot() and scsi_host_set_guard(),
which currently enabled all modes of DIF/DIX protection, minus
DIX TYPE0.
Also, update tcm_loop_submission_work() to pass struct scsi_cmnd
related protection into target_submit_cmd_map_sgls() during CDB
dispatch.

This patch adds support for DIF protection init/format support into
the FILEIO backend.
It involves using a seperate $FILE.protection for storing PI that is
opened via fd_init_prot() using the common pi_prot_type attribute.
The actual formatting of the protection is done via fd_format_prot()
using the common pi_prot_format attribute, that will populate the
initial PI data based upon the currently configured pi_prot_type.
Based on original FILEIO code from Sagi.
v1 changes:
- Fix sparse warnings in fd_init_format_buf (Fengguang)
