ubus: fix channel for active probing

Browse Source 
The IEEE802.11-2016 specification says:

[...] a Channel Number field value of 255 indicates a request
to make iterative measurements for all supported channels in the
current operating class listed in the latest AP Channel Report
received from the serving AP.

The problem with this is, no AP Channel report is sent to the STA with
the measurement request.

To scan the whole Operating class, a channel number of 0 is desired:

[...] Channel Number field value of 0 indicates a request to make
iterative measurements for all supported channels in the operating
class [...]
