NFS: Fix put_nfs_open_context
We need to grab the inode->i_lock atomically with the last reference put in
order to remove the open context that is being freed from the
nfsi->open_files list.
Fix by converting the kref to a standard atomic counter and then using
atomic_dec_and_lock()...
Thanks to Arnd Bergmann for pointing out the problem.
