cfg80211: regulatory: restore proper user alpha2

restore_regulatory_settings() should restore alpha2
as computed in restore_alpha2(), not raw user_alpha2 to
behave as described in the comment just above that code.

This fixes endless loop of calling CRDA for "00" and "97"
countries after resume from suspend on my laptop.

Looks like others had the same problem, too:
