    Backout change from using free() to g_free() in systemd patch
    
    From Lennart: Ahum, the free() calls (instead of g_free()) were
    actually placed there for a reason: the memory is allocated by
    sd_pid_get_session() and friends -- which allocate their memory with
    malloc(), and not g_malloc(). In the normal case the backend of
    g_malloc() will simply be malloc(), however if people use
    g_mem_set_vtable() this might differ. i.e. you may use g_free() and
    free() only then interchangably if g_mem_is_system_malloc() is
    TRUE. Summary: replacing free() by g_free() will work most of the
    times but is incorrect.
