nfsd4: fix file leak on open_downgrade
commit f197c27196a5e7631b89e2e92daa096fcf7c302c upstream.
Stateid's hold a read reference for a read open, a write reference for a
write open, and an additional one of each for each read+write open. The
latter wasn't getting put on a downgrade, so something like:
open RW
open R
downgrade to R
was resulting in a file leak.
Also fix an imbalance in an error path.
Regression from 7d94784293096c0a46897acdb83be5abd9278ece "nfsd4: fix
downgrade/lock logic".
