NFS: cache_lib: use complete() instead of complete_all()
There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().
The generic caching code from sunrpc is calling revisit() only once.
The usage pattern of the completion is:
waiter context waker context
do_cache_lookup_wait()
nfs_cache_defer_req_alloc()
init_completion()
do_cache_lookup()
nfs_cache_wait_for_upcall()
wait_for_completion_timeout()
nfs_dns_cache_revisit()
complete()
nfs_cache_defer_req_put()
