This fixes regression introduced by commit 8d52af6795c0 ("mei: speed up the power down flow")
In power down or suspend flow a message can still be received from the FW because the clients fake disconnection. In normal case we interpret messages w/o destination as corrupted and link reset is performed in order to clean the channel, but during power down link reset is already in progress resulting in endless loop. To resolve the issue under power down flow we discard messages silently.
