mei: clean write queues and wake waiters on disconnect

Browse source

Clean write and write_waiting queues in disconnect.
Requests in those queues are stale and processing will lead to
fat warnings.

In multi thread operations on disconnect and in FW disconnect case -
write/read/event waiters should end wait and return error.
Wake all waiters for disconnecting client to achieve that.

Drop wake all and write queue clean on reset,
as now we waking all waiters and cleaning write queues on disconnect.
No need to do it twice.
