net/mlx5: fs, add multiple prios to RDMA TRANSPORT steering domain

Browse Source 
RDMA TRANSPORT domains were initially limited to a single priority.
This change allows the domains to have multiple priorities, making
it possible to add several rules and control the order in which
they're evaluated.
