mac80211: remove WARN_ON() from ieee80211_hw_config
ieee80211_hw_config can return an error when the hardware
has rfkill enabled. A WARN_ON() is too harsh for this
failure as it is a valid scenario. Only comment this warning
as we would like to have it back when rfkill is integrated into
mac80211.
Also reintroduce propagation of error if ieee80211_hw_config fails
in ieee80211_config_beacon.
This patch partially reverts patch:
