wifi: mwifiex: Fix HT40 bandwidth issue.

Browse Source 
This patch addresses an issue where, despite the AP supporting 40MHz
bandwidth, the connection was limited to 20MHz. Without this fix,
even if the access point supports 40MHz, the bandwidth after
connection remains at 20MHz. This issue is not a regression.
