net/mlx5: Ensure fw pages are always allocated on same NUMA

Browse Source 
[ Upstream commit f37258133c1e95e61db532e14067e28b4881bf24 ]

When firmware asks the driver to allocate more pages, using event of
give_pages, the driver should always allocate it from same NUMA, the
original device NUMA. Current code uses dev_to_node() which can result
in different NUMA as it is changed by other driver flows, such as
mlx5_dma_zalloc_coherent_node(). Instead, use saved numa node for
allocating firmware pages.

Fixes: 311c7c71c9 ("net/mlx5e: Allocate DMA coherent memory on reader NUMA node")
