selftests/bpf: test_xsk: Move exit_with_error to xskxceiver.c

exit_with_error() isn't called by test_xsk.c. It shouldn't be called
in the future either, since some resources need to be cleaned before
exiting when an error occurs.

Move the definition of exit_with_error() to xskxceiver.c, where it's
still used.
