    drm/xe: Prefer struct_size over open coded arithmetic
    
    This is an effort to get rid of all multiplications from allocation
    functions in order to prevent integer overflows [1].
    
    As the "q" variable is a pointer to "struct xe_exec_queue" and this
    structure ends in a flexible array:
    
    struct xe_exec_queue {
            [...]
            struct xe_lrc lrc[];
    };
    
    the preferred way in the kernel is to use the struct_size() helper to
    do the arithmetic instead of the argument "size + size * count" in the
    kzalloc() function.
    
    This way, the code is more readable and more safer.
