Pavel Tatashin 684ad537ab timekeeping: Prevent false warning when persistent clock is not available ...

On arches with no persistent clock a message like this is printed during
boot:

[    0.000000] Persistent clock returned invalid value

The value is not invalid: Zero means that no persistent clock is available
and the absence of persistent clock should be quietly accepted.

Fixes: 3eca993740 ("timekeeping: Replace read_boot_clock64() with read_persistent_wall_and_boot_offset()")
