[PATCH] net: wireless: ath: ath10k: remove unnecessary code

[Gustavo A. R. Silva]

The name of an array used by itself will always return the array's address.
So these tests will always evaluate as false and therefore the _return_
will never be executed.

I don't understand the commit log, especially what does "The name of an
array used by itself" mean?

The array fields in struct wmi_start_scan_arg that are checked here are
fixed size arrays so they can never be NULL.

Maybe that helps rephrasing this commit message.
