Unfortunately I don't own one of these cards, and mwifiex is fullmac so
there's no hwsim either, so it was source and compile only. The added checks
only skip elements too short for what the driver later reads, so they
shouldn't affect a well-formed beacon.

To skip the one malformed optional element and keep parsing the rest of the
beacon, like the FH/DS/CF/IBSS cases just above in the same loop. Happy to
switch to -EINVAL if you'd rather reject the whole BSS.
