    cbfstool: cbfs-mkstage.c: Free `buffer` on error path
    Cppcheck warns about a memory leak, present since adding romtool,
    the former name of cbfstool, in commit 5d01ec0f.
        $ cppcheck --version
        Cppcheck 1.59
        [cbfs-mkstage.c:170]: (error) Memory leak: buffer
    Indeed the memory pointed to by `buffer` is not free’d on the error path,
    so add `free(buffer)` to fix this.
