The remote port is removed too late from fcloop_nports list. Remove it
when port is unregistered.
This prevents a busy loop in fcloop_exit, because it is possible the
remote port is found in the list and thus we will never progress.
The kernel log will be spammed with
nvme_fcloop: fcloop_exit: Failed deleting remote port
nvme_fcloop: fcloop_exit: Failed deleting target port
