branch: fix a leak in check_tracking_branch

Let's fix a leak we have in check_tracking_branch() since the function
was introduced in 41c21f22d0 (branch.c: Validate tracking branches with
refspecs instead of refs/remotes/*, 2013-04-21).

The leak can be reviewed with:

   $ git remote add local .
   $ git update-ref refs/remotes/local/foo HEAD
   $ git branch --track bar local/foo

   Direct leak of 24 byte(s) in 1 object(s) allocated from:
       ... in xrealloc wrapper.c
       ... in strbuf_grow strbuf.c
       ... in strbuf_add strbuf.c
       ... in match_name_with_pattern remote.c
       ... in query_refspecs remote.c
       ... in remote_find_tracking remote.c
       ... in check_tracking_branch branch.c
       ... in for_each_remote remote.c
       ... in validate_remote_tracking_branch branch.c
       ... in dwim_branch_start branch.c
       ... in create_branch branch.c
       ... in cmd_branch builtin/branch.c
       ... in run_builtin git.c
