[patch net 2/2] mlxsw: spectrum_qdisc: Don't use variable array in mlxsw_sp_tclass_congestion_enable

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

Resolve the sparse warning:
"sparse: Variable length array is used."
Use 2 arrays for 2 PRM register accesses.

Fixes: 96f17e0776c2 ("mlxsw: spectrum: Support RED qdisc offload")
