[ Upstream commit e73fa11a356ca0905c3cc648eaacc6f0f2d2c8b3 ]
Previously, in ondemand read scenario, if the anonymous fd was closed by
user daemon, inflight and subsequent read requests would return EIO.
As long as the device connection is not released, user daemon can hold
and restore inflight requests by setting the request flag to
CACHEFILES_REQ_NEW.
