Subject: [PATCH 1051/1051] wifi: mt76: mt7915: set channel after sta is
 associated to adjust switch reason

when sta is associated to AP operating in DFS channel, a channel
setting operation is required to change the channel switch reason
from CH_SWTICH_DFS to CH_SWITCH_NORMAL.
Note that the switch reason for DFS channel during authentication is
CH_SWITCH_DFS since the DFS state is still USABLE at that point
