qcacld-3.0: Fix mem leak in hdd_wlan_start_modules

Browse source 
In function hdd_wlan_start_modules, when hdd_configure_cds
return error, driver does not free memory buffer
hdd_ctx->target_hw_name in hdd_update_hw_sw_info, which is
allocated when the driver is in the open state.

Fix is to free the memory for hdd_ctx->target_hw_name buffer
and set to NULL.
