netfs: Drop the was_async arg from netfs_read_subreq_terminated()

Browse Source 
Drop the was_async argument from netfs_read_subreq_terminated().  Almost
every caller is either in process context and passes false.  Some
filesystems delegate the call to a workqueue to avoid doing the work in
their network message queue parsing thread.

The only exception is netfs_cache_read_terminated() which handles
completion in the cache - which is usually a callback from the backing
filesystem in softirq context, though it can be from process context if an
error occurred.  In this case, delegate to a workqueue.
