James Prestwood 5c96e1e81e auto-t: fix SAQuery-spoofing test
This test occationally failed due to a badly timed DBus scan
triggering right when hwsim tried sending out the spoofed frame.
This caused mac80211_hwsim to reject CMD_FRAME when the timing
was just right.

Rather than always starting a DBus scan we can rely on periodic
scans and only DBus scan if there are no networks in IWD's list.
A scanning check was also added prior to sending out the frame
and if true we wait for not scanning. This is more paranoia than
anything.
