After an upgrade to MinGW version 13, compilation breaks:

In function 'rte_bbdev_queue_ops_dump':
lib/bbdev/rte_bbdev.c:1269:63: error:
        '%s' directive argument is null [-Werror=format-overflow=]
        fprintf(f, "  Enqueue Status Counters %s %" PRIu64 "\n",

The enqueue status string may be null if the index is too high,
because RTE_BBDEV_ENQ_STATUS_SIZE_MAX is defined to include
padding for future enum insertion.
This padding case must be checked
to avoid printing a dump of a non-existing status.
