commit 1da6cfac736285ac822b1f48aec327ce42822356

libibumad/umad.c: In get_port, ignore sysfs rate file errors
    
    This can cause ibpanic in ibstat when width is not set properly
    as can occur when QSPF is not plugged into port.
    
    ibpanic: [7851] main: stat of IB device 'mlx5_1' failed: Invalid argument
    
    It's caused by kernel sysfs.c:show_rate returning -EINVAL
    and that error being treated as failure in umad.c:get_port.
    With this change, Rate is displayed as 0 with ibstat for this scenario.
