ACPI: CPPC: Check cpc_read() return values consistently
Callers of cpc_read() ignore its return value, which can lead
to using uninitialized or stale values when the read fails.
Fix this by consistently checking cpc_read() return values in
cppc_get_perf_caps(), cppc_get_perf_ctrs(), and cppc_get_perf().
