mac80211: avoid NULL ptr deref when finding max_rates in PID and minstrel
commit 621ad7c96aa138cfeab53cd4debc5a4e08b2189b upstream.
"There is another problem with this piece of code. The sband will be NULL
after second iteration on single band device and cause null pointer
dereference. Everything is working with dual band card. Sorry, but i
don't know how to explain this clearly in English. I have looked on the
second patch for pid algorithm and found similar bug."
