[PATCH 3/3] clone: use free_refspec() to free refspec list

Using free() on a refspec was always leaky, as its string
fields also need freed. But it became more so when ad00f128d
(clone: respect configured fetch respecs during initial
fetch, 2016-03-30) taught clone to create a list of
refspecs, each of which need to be freed.

It's doubtful anyone cares, as this is right before program exit anyway.
But if we're going to bother to free(), we may as well do it right.
