scsi: qla2xxx: Fix Name Server logout detection on FWI2 adapters

In the CS_PORT_LOGGED_OUT case of qla2x00_chk_ms_status(), the
FWI2-capable branch compared ms_pkt->loop_id.extended against NPH_SNS to
decide whether the Name Server had logged out. On FWI2 and later
adapters the response is a ct_entry_24xx / ct_entry_24xx_ext, where
loop_id.extended (via the legacy ms_iocb_entry_t view) aliases offset 8,
which is comp_status, not nport_handle (offset 10). As this code runs
under CS_PORT_LOGGED_OUT, the field read back 0x29 (CS_PORT_LOGGED_OUT)
and the comparison against NPH_SNS (0x7fc) was always false.

As a result the driver never recognized a Name Server logout on FWI2/
29xx adapters: it returned the generic QLA_FUNCTION_FAILED instead of
QLA_NOT_LOGGED_IN and skipped setting LOOP_RESYNC_NEEDED /
LOCAL_LOOP_UPDATE, so the fabric rediscovery triggered by an SNS logout
did not happen.

Read nport_handle from the ct_entry_24xx layout (offset 10) instead.
nport_handle is at the same offset in ct_entry_24xx and
ct_entry_24xx_ext, so a single cast covers 24xx-class and 29xx. The
non-FWI2 branch keeps using loop_id.extended, which is correct for the
ms_iocb_entry_t response on those adapters.
