pNFS: Fix a reference leak in _pnfs_return_layout
IF NFS_LAYOUT_RETURN_REQUESTED is not set, then we currently exit without freeing the list of invalidated layout segments, leading to a reference leak. Reported-by: Olga Kornievskaia <aglo@umich.edu> Fixes: 24408f5282 ("pNFS: Fix bugs in _pnfs_return_layout") Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
