Use InfiniBandClass from procfs library (#1396)

Browse source 
Parsing the sysfs files for InfiniBand was added to the procfs library
(see https://github.com/prometheus/procfs/pull/164).

Therefore use `InfiniBandClass` from the procfs library instead of
parsing sysfs itself.

If the port counter return `N/A (no PMA)` no metric will be returned
(instead of returning 0 for this metric.
