Hi Luca, I guess above line caused WCN6750 crash.
For a quick try, you can change it back to "config->num_vdevs = 4".

A more reasonable fix coule be to define a dedicated function like 
ath11k_init_wmi_config_wcn6750() so wcn6750 doesn't use the same 
function as QCA6390 and WCN6855, and everything changed in this patch 
will not affect wcn6750.
