scsi: lpfc: fix remoteport access
The addition of a spinlock in lpfc_debugfs_nodelist_data() introduced a bug that lets us not skip NULL pointers correctly, as noticed by gcc-8: drivers/scsi/lpfc/lpfc_debugfs.c: In function 'lpfc_debugfs_nodelist_data.constprop': drivers/scsi/lpfc/lpfc_debugfs.c:728:13: error: 'nrport' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (nrport->port_role & FC_PORT_ROLE_NVME_INITIATOR) This changes the logic back to what it was, while keeping the added spinlock.
