crimson: Trigger a wake operation via acquire_throttle

The background recovery is not showing any progress for crimson when
crimson_osd_scheduler_concurrency is set more than 0. After read the
source code it seems the recovery was not showing any progress because
initially the queue is empty it was waiting for a future that eventually
available after call wake() so call a wake() operation to return a future.
