DFS: Change vht_capab according to user requested bandwidth

Browse source 
There are different CHAN_SWITCH flows for DFS and non-DFS channels.
Non-DFS one saves previous BW value in iface->conf, but DFS flow
replaces it with a new user requested value. Setting a non-DFS channel
after a DFS one with BW = 160 would have resulted in a mismatch between
the saved BW and vht_capab (if VHT160 was not included by default). This
would have led to a check fail in the hostapd_set_freq_params()
function.
