net: stmmac: Fix NAPI poll in TX path when in multi-queue
Commit 8fce33317023 introduced the concept of NAPI per-channel and
independent cleaning of TX path.
This is currently breaking performance in some cases. The scenario
happens when all packets are being received in Queue 0 but the TX is
performed in Queue != 0.
Fix this by using different NAPI instances per each TX and RX queue, as
suggested by Florian.
Changes from v2:
- Only force restart transmission if there are pending packets
Changes from v1:
- Pass entire ring size to TX clean path (Florian)
