wlan: IBSS: Select proper cbmode if DOT11AC is not supported.

If dot11mode in INI file is auto/11ac and WLAN_FEATURE_11AC
is defined, the phymode is used as 11ac for selecting cbmode
even if DOT11AC feature is not supported by Driver/FW.
This leads to invalid cbmode selection and IBSS is
not started.

Adds a check to set phymode as 11ac during cbmode selection only
if DOT11AC feature is supported by Driver/FW.
