NFS/pnfs: Don't use RPC_TASK_CRED_NOREF with pnfs

Browse source 
When we're doing pnfs then the credential being used for the RPC call
is not necessarily the same as the one used in the open context, so
don't use RPC_TASK_CRED_NOREF.

Fixes: 6129650720 ("NFSv4: Avoid referencing the cred unnecessarily during NFSv4 I/O")
