scsi: lpfc: Fix nvmet node ref count handling
When unloading the driver, the NVMET driver would wait the full 30 seconds for its UNMAPPED initiator node to get removed before continuing with the unload process. NVMEI worked correctly. For each rport put into UNMAPPED or MAPPED state by NVMET, the driver puts a reference on the NDLP. The difference is that NVMEI has a unregister call for its rports and the extra reference is removed in the unregister process. For NVMET, the driver has to remove the reference explicitly when dropping out of UNMAPPED or MAPPED because there is no unregister call. Add a call to lpfc_nlp_put on the ndlp when NVMET and the old state was UNMAPPED or MAPPED.
