Use error message thrown by timedate1 service

If NTP is set, SetTime from timedate1 service throws
a standard error. Current code was throwing a custom error
and it was not much helpful. Correct thing is to re-throw
what timedate1 throws.

Also, current code was gating the SetTime request if the
time mode was NTP. This has been removed now and the decision
is left to timedate1 service now on whether to allow setting
the time or not when NTP is enabled.
