scsi: fnic: Initialize the NVMe local port info before registering

nvfnic_add_lport() declares struct nvme_fc_port_info on the stack and
fills in four of its five members, leaving dev_loss_tmo holding whatever
the stack happened to contain before the call.  The structure is then
handed to nvme_fc_register_localport().

nvfnic_add_tport(), which registers the remote port a few lines further
down, memsets its own struct nvme_fc_port_info first, so only the local
port path passes uninitialized data across the transport interface.

The NVMe/FC transport documents dev_loss_tmo as "Used only on a
remoteport" and does not read it in nvme_fc_register_localport(), so
there is no behavioural change today.  Initialize the structure anyway:
the driver must not depend on which members the transport happens to
consume, and any member added to struct nvme_fc_port_info later would
silently start out as stack garbage.
