Incorrect ptypes list causes buffer overflow for Address Sanitizer
run and a tap device. The last element in the ptypes lists to be
to "RTE_PTYPE_UNKNOWN" for rte_eth_dev_get_supported_ptypes().
In rte_eth_dev_get_supported_ptypes(), the loop iterates until it
finds "RTE_PTYPE_UNKNOWN" to detect last element of the ptypes array.
Fix tap_dev_supported_ptypes_get() method to return correct lists.
