NFSv4.1: Enable state protection

Use the EXCHGID4_FLAG_BIND_PRINC_STATEID exchange_id flag to enable
stateid protection. This means that if we create a stateid using a
particular principal, then we must use the same principal if we
want to change that state.
IOW: if we OPEN a file using a particular credential, then we have
to use the same credential in subsequent OPEN_DOWNGRADE, CLOSE,
or DELEGRETURN operations that use that stateid.
