[ Upstream commit 1d5e9f80ab021e3e1f9436627a4ad07a143ccb2c ]
When channel contexts are used, there's no global power level
(the power_level is always 0). Use the per-interface TX power
in mac80211_hwsim to have a proper setting for both cases.
This fixes the bgscan_simple and bgscan_learn test cases when
the number of channels advertised by hwsim is >1 by default.
