NFSD: fix management of pending async copies
Currently the pending_async_copies count is decremented just
before a struct nfsd4_copy is destroyed. After commit aa0ebd21df9c
("NFSD: Add nfsd4_copy time-to-live") nfsd4_copy structures sticks
around for 10 lease periods after the COPY itself has completed,
the pending_async_copies count stays high for a long time. This
causes NFSD to avoid the use of background copy even though the
actual background copy workload might no longer be running.
In this patch, decrement pending_async_copies once async copy thread
is done processing the copy work.
Fixes: aa0ebd21df9c ("NFSD: Add nfsd4_copy time-to-live")
