Subject: [PATCH] async_client: Don't request a write lock for crypto based
 requests.

The crypto state machine is in the base client behind a separate lock so
there's no need to require write access.

This removes a deadlock if we're trying to send an encrypted message
from a event emitter callback, since emitting an event fetches a read
lock as well.
