net/mlx5e: Add new prio for promiscuous mode

An optimization for promiscuous mode adds a high-priority steering
table with a single catch-all rule to steer all traffic directly to
the TTC table.

However, a gap exists between the creation of this table and the
insertion of the catch-all rule. Packets arriving in this brief window
would miss as no rule was inserted yet, unnecessarily incrementing the
'rx_steer_missed_packets' counter and dropped.

This patch resolves the issue by introducing a new prio for this
table, placing it between MLX5E_TC_PRIO and MLX5E_NIC_PRIO. By doing
so, packets arriving during the window now fall through to the next
prio (at MLX5E_NIC_PRIO) instead of being dropped.
