ShellPkg: Update behavior for GetTime() errors.

Please find the attached patch that fixes the ShellPkg when gRT->GetTime() returns an error (eg: early UEFI platform bringup with a RTC controller that is not supported).
On some platforms, gRT->GetTime() might not return EFI_SUCCESS. The Shell must check the return status before to assume the returned time is valid.
