util: pidfile: Sanitize return values of virPidFileReadPathIfAlive
The callers don't actually use the returned errno for reporting errors. Additionally virFileResolveAllLinks returns -1 rather than -errno on error thus you'd get a spurious EPERM even on other errors. Don't try to return errno in this case.
