4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit 8561fb31a1f9594e2807681f5c0721894e367f19 upstream.

With Androidx86 8.1, wificond returns "failed to get
nl80211_sta_info_tx_failed" and wificondControl returns "Invalid signal
poll result from wificond". The fix is to OR sinfo->filled with
BIT_ULL(NL80211_STA_INFO_TX_FAILED).

This missing bit is apparently not needed with NetworkManager, but it
does no harm in that case.
