connect.c: do not leak "conn" after showing diagnosis

When git_connect() is called to see how the URL is parsed for
debugging purposes with CONNECT_DIAG_URL set, the variable conn is
leaked.  At this point in the codeflow, it only has its memory and
no other resource is associated with it, so it is sufficient to
clean it up by just freeing it.
