[PATCHv3 4/4] clone: use free_refspec() to free refspec list

["SZEDER Gábor" <szeder.dev@gmail.com>]

From: Jeff King <peff@peff.net>

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.

[sg: adjusted the function parameters.]
