iwd release 1.30 onwards cannot find available networks

[Bruno Dantas <dantas@airpost.net>]

I was a happy iwd user through release 1.29. From 1.30 onwards (including the latest version 2.0) I had to switch to wpa_supplicant because in most (but, strangely, not all) locations where I go, iwd fails to find any available networks ("sudo iwctl station wlan0 get-networks" says "No networks available").

Today I finally got around to doing a git bisect to pinpoint the regression. The bisect concluded with this:

dfcba7c83c60f1a99ecf6f1424e97bf89fcab38e is the first bad commit

    wiphy: track GET_REG ID
    
    Keep track of the GET_REG call so it can be canceled if the wiphy
    goes down.

In case it's helpful, my machine is an X230 ThinkPad with coreboot, linux kernel version 5.15.10, running Tiny Core Linux 13.1 x86_64. My wireless card is Intel Dual Band Wireless-AC 7265. If you guys need any more information, I'd love to help.

Please fix this regression if possible. I'd love to go back to using iwd in the future.

Happy hacking!
