[PATCH] rvmet-fcloop: Remove remote port from list when unlinking

The remote port is never removed from fcloop_nports list. During module
unloading it's possible to end up an busy loop in fcloop_exit, because
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
