[PATCH net-next v5 2/9] net: ethernet: ti: cpsw_ale: return ALE index in cpsw_ale_add_vlan()

[Roger Quadros <rogerq@kernel.org>]

Policer helpers will be interested to know what ALE index was used
for the added VLAN entry. So return the ALE index instead of zero
on success.

Modify existing users to check for less than zero as error case.
