ofed_scripts/show_irq_affinity.sh: Add CPU number to the script output

Example: show_irq_affinity.sh mlx5_0 show_cpu_number Note: without the show_cpu_number flag, the output will be as it was. output before: 124: 0,00000001 125: 0,00000002 126: 0,00000004 127: 0,00000008 128: 0,00000010 129: 0,00000020 130: 0,00000040 output after: 124 (cpu #0): 0,00000001 125 (cpu Mellanox#1): 0,00000002 126 (cpu Mellanox#2): 0,00000004 127 (cpu Mellanox#3): 0,00000008 128 (cpu Mellanox#4): 0,00000010 129 (cpu Mellanox#5): 0,00000020 130 (cpu Mellanox#6): 0,00000040 Signed-off-by: Guy Twig <[email protected]> Signed-off-by: Vladimir Sokolovsky <[email protected]>
