mei: amthif: discard not read messages
commit 9d04ee11db7bf0d848266cbfd7db336097a0e239 upstream.
When a message is received and amthif client is not in reading state
the message is ignored and left dangling in the queue. This may happen
after one of the amthif host connections is closed w/o completing the
reading. Another client will pick up a wrong message on next read
attempt which will lead to link reset.
To prevent this the driver has to properly discard the message when
amthif client is not in reading state.
