psu-ng: Don't log brownout error if all PSUs are missing

During a BMC reboot at runtime, the PSUs may not exist yet on D-Bus.
Therefore, add a check to ignore if all PSUs are marked as not present,
or the total of PSUs is 0, and not log a brownout error. Therefore to
log a brownout error, at least one PSU must report a AC loss VIN fault.

Tested: Verified a brownout error is not logged on a reboot at runtime
even though the number of PSUs was 0. Also a brownout error was not
logged when all PSUs were manually set to not present.
