Hmm, actually ... I suspect this didn't introduce a bug but rather
unmasked one in iwlwifi/mac80211 interaction.

Are you sure this only happens after suspend/resume? It seems like it
would always happen? At least if there was a beacon in the scan results
already, which should probably always be the case...

Can you enable iwlwifi debugging and set the iwlwifi module parameter
debug=0x40000000 ? I have a feeling you'll see something like
"PASSIVE_NO_RX" in there.
