Fix mesh 6 GHz incorrect channel bandwidth

Browse source 
When the wiphy supports multiple bands and reports different capability
values between 5 GHz and 6 GHz channels, the 6 GHz mesh interface is
unable to correctly map the channel width in function
ibss_mesh_setup_freq(). This issue arises because the modes of 5 GHz and
6 GHz interfaces are the same (HOSTAPD_MODE_IEEE80211A) in supported
modes.

To address this, use function get_mode() to determine the appropriate
mode during mesh setup. This will iterates through all the hw_features
sets and ensures compatibility with the band of the channel supported in
hw_features set.
