[ Upstream commit ff93b71a3eff25fe9d4364ef13b6e01d935600c6 ]
Although in practice this can not occur (since IPv4 and IPv6 are the only two cases currently supported), it is cleaner to avoid uninitialized variable warnings.
Addresses smatch warning: fs/cifs/cifs_swn.c:468 cifs_swn_store_swn_addr() error: uninitialized symbol 'port'.
