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: 3eca993740b8 ("timekeeping: Replace read_boot_clock64() with read_persistent_wall_and_boot_offset()")
