hostapd: fix opclass during CSA with DFS channels

Browse Source 
During CSA with DFS channels, disable, enable interface
is a part of the algorithm.
When interface was enabled old operating class before switch
and new channel were used causing mismatch in
configured_fixed_chan_to_freq function.

Example of log when switch from channel 157 to 108 was triggered:
"Could not convert op_class 124 channel 108 to operating frequency"

Fixes: WIFI-13385
