mt76: fix monitor rx FCS error in DFS channel

Browse Source 
When setup monitor mode in DFS channel, mt76 send CH_SWITCH_DFS to
fw for channel config. This would cause rx performance bad while
monitoring frames. Settings CH_SWITCH_NORMAL in monitor mode would
get the same performance as normal channels.
