NFSv4: Fix a use-after-free problem in open()
If we interrupt the nfs4_wait_for_completion_rpc_task() call in
nfs4_run_open_task(), then we don't prevent the RPC call from
completing. So freeing up the opendata->f_attr.mdsthreshold
in the error path in _nfs4_do_open() leads to a use-after-free
when the XDR decoder tries to decode the mdsthreshold information
from the server.
Fixes: 82be417aa37c0 (NFSv4.1 cache mdsthreshold values on OPEN)
