[PATCH net-next 2/2] net: ethernet: qualcomm: Constify "queue_map" in ppe_ring_queue_map_set()

[Krzysztof Kozlowski]

"queue_map" is a pointer to "u32" and is not modified by the
ppe_ring_queue_map_set() function, thus can be made a pointer to const to
indicate that function is treating the pointed value read-only.  This in
general makes the code easier to follow and a bit safer.
