Yongseok Koh 12d468a62b net/mlx5: fix instruction hotspot on replenishing Rx buffer
On replenishing Rx buffers for vectorized Rx, mbuf->buf_addr isn't needed
to be accessed as it is static and easily calculated from the mbuf address.
Accessing the mbuf content causes unnecessary load stall and it is worsened
on ARM.
