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.
