From: Magnus Karlsson <magnus.karlsson@intel.com>

Print the correct error codes when exiting the test suite due to some
terminal error. Some of these had a switched sign and some of them
printed zero instead of errno.

Fixes: facb7cb2e909 ("selftests/bpf: Xsk selftests - SKB POLL, NOPOLL")
Acked-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com>
