[Devel] [PATCH RH8 4/5] unix: define and set show_fdinfo only if procfs is enabled

[Vasily Averin]

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")
