ipa: protect against multiple subsequent calls to ipa_client_conn_close()

This would create linked list coruption in osmo_fd_unregister().

The fact that multiple calls of osmo_fd_unrgeister() on the same fd
happen is due to the fact that ipaccess_drop() and others already close
the file descriptor.
