[PATCH AUTOSEL 4.19 2/5] mac80211: fix user-power when emulating chanctx

From: Ben Greear <redacted>

[ Upstream commit 9b15c6cf8d2e82c8427cd06f535d8de93b5b995c ]

ieee80211_calc_hw_conf_chan was ignoring the configured
user_txpower.  If it is set, use it to potentially decrease
txpower as requested.
