Interface Errors percentage over 100%

[andytlc68]

Using the check_nwc_health (10.0.0.2), mode interface-health, I obtain weird values of percentage of errors in /out. It exceeds the 100% (for example 165%).
In my opinion, the formula used to compute this percentage is not correct, because it doesn't take into account the number of errors in the denominator. So I fix the code in this way:

Percentage of Percent of Errors In:

$self->{inputErrorsPercent} = $self->{delta_ifInPkts} == 0 ? 0 :

original: 100 * $self->{delta_ifInErrors} / $self->{delta_ifInPkts};
my fix: 100 * $self->{delta_ifInErrors} / ($self->{delta_ifInErrors} + $self->{delta_ifInPkts});

Percentage of Percent of Errors Out:

$self->{outputErrorsPercent} = $self->{delta_ifOutPkts} == 0 ? 0 :

original: 100 * $self->{delta_ifOutErrors} / $self->{delta_ifOutPkts};
my fix: 100 * $self->{delta_ifOutErrors} / ($self->{delta_ifOutErrors} + $self->{delta_ifOutPkts});

If you are agree with me, I propose a fix for the next release.
Hope this helps
