qcacld-3.0: Initialize sap ch_width by Max ch_width

Browse source 
Initialize sap bw as MAX BW in
policy_mgr_valid_sap_conc_channel_check() as
wlansap_get_csa_chanwidth_from_phymode() take care
of selecting BW for sap and it has a check that will
take minimum of selected BW and initialized BW.
If this BW is not initialized with Max BW then in cases
where original BW is 0 (20 Mhz) (cases such as channel
switch happens from 2.4Ghz to 5Ghz), the above mentioned
check will result in selected BW being 0 (20 Mhz) for
non-DBS HW.
