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: 08ee1559052b ("prctl: cfi: change the branch landing pad prctl()s to be more descriptive")

[pjw@kernel.org: change the patch description to note that although this is a uABI change, it does not break the uABI]
