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.
