media: cec: copy sequence field for the reply

commit 13cbaa4c2b7bf9f8285e1164d005dbf08244ecd5 upstream.

When the reply for a non-blocking transmit arrives, the sequence
field for that reply was never filled in, so userspace would have no
way of associating the reply to the original transmit.

Copy the sequence field to ensure that this is now possible.
