Wey-Yi Guy 137ce797e2 iwlwifi: do not re-configure HT40 after associated 
The ht40 setting should not change after association unless channel switch

This fix a problem we are seeing which cause uCode assert because driver
sending invalid information and make uCode confuse

Here is the firmware assert message:
