lib: sbi_pmu: check for index overflows
sbi_pmu_ctr_cfg_match() receives data from a lower privilege level mode.
We must catch maliciously wrong values.
We already check against total_ctrs. But we do not check that total_ctrs is
less than SBI_PMU_HW_CTR_MAX + SBI_PMU_FW_CTR_MAX.
Check that the number of hardware counters is in the valid range.
