mac80211: fix txpower when using DFS channels

With this patch, txpower for the PHY is applied when configuring the PHY
instead of the VIF. Otherwise, the configured txpower is not applied for
the first initialized VIF when using DFS channels, as it is currently
applied too early when the CAC hasn't finished.
