arm64: gcs: Return -EPERM not -EBUSY for prctl() locking failures
When we refuse to perform a GCS configuration change due to locking we
currently return -EBUSY which is an odd error code to return. While the
selftest does currently check for this it is unlikely that we have any
practical users relying on the behaviour at this point so let's change
to return the more descriptive -EPERM instead like x86.
