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.
