mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4
[ Upstream commit 651b9920d7a694ffb1f885aef2bbb068a25d9d66 ]
This ensures that mac80211 allocated management frames are properly
aligned, which makes copying them more efficient.
For instance, mt76 uses iowrite32_copy to copy beacon frames to beacon
template memory on the chip.
Misaligned 32-bit accesses cause CPU exceptions on MIPS and should be
avoided.
