After waking from D3, we set the iPN given by the firmware.
For some reason, CIPHER_SUITE_AES_CMAC was missed.
That caused copying garbage to the iPN - causing false replays.

(since 'seq' is on the stack, and the iPN from the firmware
was not copied into it, it contains garbage which later is
copied to the iPN key).
