qcacmn: Update the connect ies to prevent 40 MHz roam

If "override_ht20_40_24g" ini is set, the host driver disables
the HT40/HE40 caps for 2.4 GHz after connection via SET IE. The
firmware uses this for roam. However, if reassoc comes from userspace
with the HT40 cap different from the initial connect, then host
does not update the IEs based on new cap. This leads to mismatch
between user configuration and firmware roam.

To fix this, modify and send the HE40/HT40 caps via SET IE for
every connect request. Reset it after disconnection to the default
self cap.
