wifi: ieee80211: check for NULL in ieee80211_mle_size_ok()

BugLink: https://bugs.launchpad.net/bugs/2076435

[ Upstream commit b7793a1a2f370c28b17d9554b58e9dc51afcfcbd ]

For simplicity, we may want to pass a NULL element, and
while we should then pass also a zero length, just be a
bit more careful here.
