Syntax error vcl_hit fetch

[askibinski]

vcl_hit does a deliver (fetch), but this is not allowed, see: https://varnish-cache.org/docs/trunk/users-guide/vcl-built-in-subs.html

Should be:

return (deliver);

[NITEMAN]

It's allowed on Varnish 4, nevertheless there is an update on the way to make it compatible with varnish 5
