lib/timestamp.c: only log "Timestamp table full" once
If the timestamp table gets corrupted (separate issue), the
timestamp_sync_cache_to_cbmem() function may add a large number of bogus
timestamp entries.
This causes a flood of "ERROR: Timestamp table full". With logs going
to a serial console, this renders the system essentially unbootable.
There really isn't a need to log that more than once, so log it when the
last slot in the timestamp table is filled.
