RDMA/counter: Add optional counter support
An optional counter is a driver-specific counter that may be dynamically enabled/disabled. This enhancement allows drivers to expose counters which are, for example, mutually exclusive and cannot be enabled at the same time, counters that might degrades performance, optional debug counters, etc. Optional counters are marked with IB_STAT_FLAG_OPTIONAL flag. They are not exported in sysfs, and must be at the end of all stats, otherwise the attr->show() in sysfs would get wrong indexes for hwcounters that are behind optional counters.
