Port issue was fixed, the hbacmd reset would take more than 8 minutes to complete.
There were conflicting NVME SGL posting/reposting responsibilities between lpfc_online()/lpfc_sli4_hba_setup() and lpfc_nvme_create_localport(). The lpfc_online() causes a REPOST on existing NVME SGLs which is not released during the fc port reset. However, lpfc_nvme_create_localport() wants to allocate new NVME buffers and post them. Both cancelled out each other which had a side effect of hosing the mailbox handling that was used to remove the sgl lists - causing multiple 60s mbx timeouts.
Fix by preserving all SGL lists over the fc port reset.
