[PATCH 1/2] examples/packet_ordering: fix format specifier for port ID

[Aarnav JP]

port_id is uint16_t, use PRIu16 instead of PRIu8 to fix
format specifier mismatch warning with GCC 15.

../examples/packet_ordering/main.c: In function 'main':
../examples/packet_ordering/main.c:740:46:

      |                                                     ^

At the time this code was introduced, port_id was a uint8_t.

This can be fixed when applying:
Fixes: f8244c6399d9 ("ethdev: increase port id range")

Same as previous comment, at the time this code was introduced,
port_id was a uint8_t.

This can be fixed when applying:
Fixes: 47523597ff6c ("examples: fix port id type")
