qcacld-3.0: Do sap channel switch with 20MHz width in 11a mode

Browse source 
Bring up SAP(2.4G)+SAP(161 channel with 11a mode)+STA mode, when STA
is connected to ref-ap on channel 36, 11a mode SAP will also switch
channel to STA's connected channel due to force scc, it will set
channel width to CH_WIDTH_40MHZ for 11a mode SAP channel switch,
actually 11a mode SAP doesn't support CH_WIDTH_40MHZ, it's wrong and
issue is introduced by
'Change-Id: I709dd35575866b7ec9fddcfb94078f114a78d1a2'.

Fix is to set channel width with 20MHz for 11a mode in function
wlansap_update_csa_channel_params().
