unix: define and set show_fdinfo only if procfs is enabled
Follow the pattern used with other *_show_fdinfo functions and only define unix_show_fdinfo and set it in proto_ops if CONFIG_PROCFS is set. Fixes: 3c32da19a858 ("unix: Show number of pending scm files of receive queue in fdinfo") Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Reviewed-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S.
