This reverts commit 8def9ec46a5fafc0abcf34489a9e8a787bca984d.
The firmware keep-alive does not cause any event in case of error
such as non acked. It's just a basic keep alive to prevent the AP
to kick-off the station due to inactivity. So let mac80211 submit
its own monitoring packet (probe/null) and disconnect on timeout.
Note: We want to keep firmware keep alive to prevent kick-off
when host is in suspend-to-mem (no mac80211 monitor packet).
Ideally fw keep alive should be enabled in suspend path and disabled
in resume path to prevent having both firmware and mac80211 submitting
periodic null packets.
This fixes non detected AP leaving issues in active mode (nothing
monitors beacon or connection).

OK.
We've made a good effort to resolve offloaded link monitoring but, it
feels like spaghetti code and isn't as reliable as letting Linux do the
link monitoring.
Let's go ahead with the reversion.
