qcacld-3.0: Fix channel weight calculation errors in ACS mode

Browse source 
Channel 13 and channel 9 can be combined to HT40. The channel weight of
13 is updated with channel 9 when chStartNum of acs_ht40_channels24_g
is 9 in sap_sort_chl_weight_ht40_24_g, however at this time the channel
weight of 9 may be already updated to SAP_ACS_WEIGHT_MAX * 2 when the
chStartNum of acs_ht40_channels24_g is 1. In such case channel weight of
13 is updated incorrectly.

When update the channel weight of 13, use original channel weight of
channel 9 and channel 13.
