45109f69a6 mac80211: fix compile error when mesh is disabled
This fixes following compile error seen when
building mac80211 with mesh disabled:

.../backports-5.15.58-1/net/mac80211/agg-rx.c: In function 'ieee80211_send_addba_resp':
...backports-5.15.58-1/net/mac80211/agg-rx.c:255:17: error: 'struct sta_info' has no member named 'mesh'
  255 |         if (!sta->mesh)
      |                 ^~

sta_info.h shows this item as being optional based on flags:

	struct mesh_sta *mesh;

Guard the check to fix this.

f96744ba6b mac80211: mask nested A-MSDU support for mesh
mac80211 incorrectly processes A-MSDUs contained in A-MPDU frames. This
results in dropped packets and severely impacted throughput.

As a workaround, don't indicate support for A-MSDUs contained in
A-MPDUs. This improves throughput over mesh links by factor 10.
