qcacld-3.0: Initialize weight_copy when weight is SAP_ACS_WEIGHT_MAX

Browse source 
When channel 4 is unsafe channel in 2.4g LTE coex ACS case,
the weight for channel 4 will be calculated as 0 by function
sap_sort_chl_weight_ht40_24_g, it's wrong because weight_copy
doesn't be initialized in this case, so acs channel select
may choose wrong channel to start sap.

Fix is to add initialization for weight_copy when weight is
SAP_ACS_WEIGHT_MAX.
