box: handle cancelling fiber waiting in WAL queue

Currently if fiber waiting in WAL queue is cancelled it will go on
writing request to WAL breaking queue order. So WAL is corrupted so that
even next Tarantool restart may fail. Unfortunately we cancel fibers on
Tarantool shutdown so the issue may arise just buy terminating Tarantool
instance.

Let's instead fail the cancelled request and all the newer request in
the queue.

Work around is to disable WAL queue by `box.cfg{wal_queue_max_size = 0}`
so that only one write request can be in the queue.

Closes #11078
