Olga Kornievskaia 982b899ba6 NFSD: fix dest to src mount in inter-server COPY 
commit 614c975017 upstream.

A cleanup of the inter SSC copy needs to call fput() of the source
file handle to make sure that file structure is freed as well as
drop the reference on the superblock to unmount the source server.

Fixes: 36e1e5ba90 ("NFSD: Fix use-after-free warning when doing inter-server copy")
