[PATCH 4/4] um: rtc: Avoid shadowing err in uml_rtc_start()

[Tiwei Bie]

From: Tiwei Bie <tiwei....@antgroup.com>

Remove the declaration of 'err' inside the 'if (timetravel)' block,
as it would otherwise be unavailable outside that block, potentially
leading to uml_rtc_start() returning an uninitialized value.

Fixes: dde8b58d5127 ("um: add a pseudo RTC")
