In the v2 review I asked to split the P2P device vif bug fix into a
separate patch with a Fixes: tag for stable backport. The null guard and
the fallback vif in brcmf_p2p_abort_action_frame() are both pre-existing
P2P bugs that should be split out and submitted as a standalone patch so
they can be backported to stable independently of the DPP feature.

Please also add a changelog below the --- line describing what changed
since v3.

Note that the P2P device vif fixes are pre-existing bugs that need to go
to the wireless tree for stable backport, separate from the DPP feature
which targets wireless-next.
