    gbproxy: Fix stored msgbs in gbproxy_flush_stored_messages
    
    Currently the last message received is patched with the meta
    information of each stored message. This can lead to invalid memory
    accesses.
    
    This commit replaces msg by stored_msg in the call to
    gbproxy_patch_bssgp.
    
    Note that the fix has not been validated by unit tests yet.
