Subject: [PATCH net-next 06/18] net: mvpp2: fix hardcoded number of rx queues

There's a dedicated #define that indicates the number of rx queues per
port per cpu, this commit removes a harcoded use of that value

This doesn't fix any runtime bugs since the harcoded value matches the
expected value.
