Richard Patel 15b4155138 riscv: cfi: reject unknown flags in PR_SET_CFI ...

prctl(PR_SET_CFI,PR_CFI_BRANCH_LANDING_PADS) silently ignored
unknown control values. Only PR_CFI_{ENABLE,DISABLE,LOCK} should
be permitted.

This changes the behavior of the uABI (fails previously accepted bits
with EINVAL).

Fixes: 08ee155905 ("prctl: cfi: change the branch landing pad prctl()s to be more descriptive")
