    hwpmc: count each AMD PMC interrupt once
    
    amd_intr() and amd_intr_v2() call pmc_ibs_intr() and then update
    kern.hwpmc.stats.intr_processed or intr_ignored.  pmc_ibs_intr() also
    updated them.  So each core PMC NMI was also counted as ignored, and
    each IBS NMI was counted as processed two times.
    
    Update the statistics only in the caller.
    
    Similarly, drop duplicate PMCDBG messages.
