[PATCH i-g-t] tests/intel/xe-oa: Use subslice_mask in pec_sanity_check

pec_sanity_check previously relied on pec counter values being 0 to ignore
missing xecores's. However we are now running into situations where pec
counters are non-zero even when xecores are missing. To get past this, use
subslice_mask (i.e. mask of present xecore's) to ignore missing xecore's.
