Make sure to print some errors if attributes cannot be appended
to a message. It is dangerous to ignore the return code from

672be730c3 wiphy: Add scheduled scan support 
Add rudimentary support for mac80211 scheduled scan feature.
This is done so that kernel support for task called "Bind
NL80211_CMD_START_SCHED_SCAN to netlink socket" from TODO
file can be tested. The current scan interval is set to 60
seconds which is probably too fast for the final version.

051f49ea85 wiphy: Tweak netdev structure creation order 
Because none of the attributes are assigned until after the DeviceAdded
signal is emitted, the signal appears with invalid properties.  For now,
move the netdev structure fill-out into the if statement.

If the netdev attributes can change, then these need to be handled
separately and appropriate signals to be sent.
