Slow suspend when wifi active

[Colin Law]

Running 17.04 (upgraded over several versions) I see a ten second additional delay on suspend if wifi is in use. Looking at the journal this looks to be debian wpa bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835648

Still present in 17.10

As the Debian says: this is fixed with wpa 2.4.1, which you can find into Bionic archive

Details on: launchpad.net/ubuntu/+source/wpa

note: wpasupplicant is known to add more trouble than security.

So closing that issue now.
