scsi: lpfc: Fix crash when nvmet transport calls host_release
When lpfc is running in NVMET mode and supports the NVME-1 addendum
changes, a LIP on a bound NVME Initiator or lipping the lpfc NVMET's link
resulted in an Oops in lpfc_nvmet_host_release.
The fix requires lpfc NVMET to maintain an additional reference on any node
structure that acts as the hosthandle for the NVMET transport. This
reference get is a one-time addition, is taken prior to the upcall of an
unsolicited LS_REQ, and is released when the NVMET transport releases the
hosthandle during the host_release downcall.
