mac80211: fix BUILD_BUG_ON() caused by misalignment on arm
On ARM alignment is done slightly different from other architectures.
struct ieee80211_tx_rate is aligned to word size, even though it only has 3
single-byte members, which triggers the BUILD_BUG_ON in
ieee80211_tx_info_clear_status
This patch marks the struct ieee80211_tx_rate as packed, so that ARM
behaves like the other architectures.
