Modified Files:
        src/sys/arch/x86/x86: pmc.c

Log Message:
switch pmc_ncounters to unsigned int.

matches userland pmc, makes it clear to static analyzers that if the loop
in pmc_nmi (for (i = 0; i < pmc_ncounters; i++) ) is not entered, then the
condition i == pmc_ncounters (== 0) is satisfied and no null derefs occur

this change only helps analyzers read the code, null deref was not possible
before.
