net/mlx4_en: Improve transmit CQ polling
Several small performance improvements in TX CQ polling,
including:
- Compiler branch predictor hints.
- Minimize variables scope.
- More proper check of cq type.
- Use boolean instead of int for a binary indication.
Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Packet-rate tests for both regular stack and XDP use cases:
No noticeable gain, no degradation.
