wifi: mac80211: fix unaligned le16 access
[ Upstream commitc53d8a5935
] The AP removal timer field need not be aligned, so the code shouldn't access it directly, but use unaligned loads. Use get_unaligned_le16(), which even is shorter than the current code since it doesn't need a cast. Fixes:8eb8dd2ffb
