Otherwise, the\nnvme_fc_xmt_ls_rsp's LLDD call to lport->ops->xmt_ls_rsp is expected to\nfail and the nvme-fc transport layer itself will directly call\nnvme_fc_xmt_ls_rsp_free instead of relying on LLDD's done callback to free\nthe lsrsp resources.\n\nUpdate the fcloop_t2h_xmt_ls_rsp routine to check remoteport->port_state.\nIf online, then lsrsp->done callback will free the lsrsp.  Else, return\n-ENODEV to signal the nvme-fc transport to handle freeing lsrsp."
