[PATCH] mellanox: mlx5: Use logging functions to reduce text ~10k/5%

[Joe Perches <joe-6d6DIl74uiNBDgjK7y7TUQ@public.gmane.org>]

The logging macros create a bit of duplicated code/text.

Use specialized functions to reduce the duplication.

(defconfig/x86-64)
$ size drivers/net/ethernet/mellanox/mlx5/core/built-in.o*
   text	   data	    bss	    dec	    hex	filename
 178634	   2059	     16	 180709	  2c1e5	drivers/net/ethernet/mellanox/mlx5/core/built-in.o.new
 188679	   2059	     16	 190754	  2e922	drivers/net/ethernet/mellanox/mlx5/core/built-in.o.old

The output changes now do not include line #,
but do include the function offset.
