[PATCH net-next v4 09/17] net: pktgen: align some variable declarations to the most common pattern

[Peter Seiderer <ps.report@xxxxxxx>]

Align some variable declarations (in get_imix_entries and get_labels) to
the most common pattern (int instead of ssize_t/long) and adjust function
return value accordingly.

Signed-off-by: Peter Seiderer <ps.report@xxxxxxx>
