CIFS: Make cifs_convert_address() take a const src pointer and a length
Make cifs_convert_address() take a const src pointer and a length so that all the strlen() calls in their can be cut out and to make it unnecessary to modify the src string. Also return the data length from dns_resolve_server_name_to_ip() so that a strlen() can be cut out of cifs_compose_mount_options() too.
