Merge patch series "Update lpfc to revision 14.4.0.5"

Justin Tee <[e-mail]> says:

Update lpfc to revision 14.4.0.5

This patch set contains bug fixes related to HBA state clean ups, FCP
discovery on older adapters, kref imbalances, log message improvements,
and support for a new diagnostic loopback testing mode.

The patches were cut against Martin's 6.12/scsi-queue tree.
