SAE: Check for invalid Rejected Groups element length explicitly on STA

Instead of practically ignoring an odd octet at the end of the element,
check for such invalid case explicitly. This is needed to avoid a
potential group downgrade attack.

Fixes: 444d76f74f65 ("SAE: Check that peer's rejected groups are not enabled")
