net/mlx5e: Use right API to free bitmap memory

Use bitmap_free() to free memory allocated with bitmap_zalloc_node().
This fixes memtrack error:
  mtl rsc inconsistency: memtrack_free: .../drivers/net/ethernet/mellanox/mlx5/core/en_main.c::466: kfree for unknown address=0xFFFF0000CA3619E8, device=0x0
