iwlwifi: mvm: add debugfs entry with the number of net-detect scans

Browse source 
Our testers need to know the number of scans performed while in
net-detect mode before the device wakes up.  The firmware already
passes this information to the driver, so we can save it and report it
in a debugfs entry.
