[PATCH AUTOSEL 4.18 18/76] nl80211: Fix nla_put_u8 to u16 for NL80211_WMMR_TXOP

[Sasha Levin]

From: Haim Dreyfuss <haim.dreyfuss@xxxxxxxxx>

[ Upstream commit d3c89bbc7491d5e288ca2993e999d24ba9ff52ad ]

TXOP (also known as Channel Occupancy Time) is u16 and should be
added using nla_put_u16 instead of u8, fix that.

Fixes: 50f32718e125 ("nl80211: Add wmm rule attribute to NL80211_CMD_GET_WIPHY dump command")
