nfsd4: remember to put RW access on stateid destruction
commit 499f3edc23ca0431f3a0a6736b3a40944c81bf3b upstream.
Without this, for example,
open read
open read+write
close
will result in a struct file leak.
Regression from 7d94784293096c0a46897acdb83be5abd9278ece "nfsd4: fix
downgrade/lock logic".
