wifi: cfg80211: avoid leaking stack data into trace

[ Upstream commit 334bf33eec5701a1e4e967bcb7cc8611a998334b ]

If the structure is not initialized then boolean types might be copied
into the tracing data without being initialised. This causes data from
the stack to leak into the trace and also triggers a UBSAN failure which
can easily be avoided here.
