pktgen: fix module unload for good

[ Upstream commit d4b1133558e0d417342d5d2c49e4c35b428ff20d ]

commit c57b5468406 (pktgen: fix crash at module unload) did a very poor
job with list primitives.

1) list_splice() arguments were in the wrong order

2) list_splice(list, head) has undefined behavior if head is not
initialized.

3) We should use the list_splice_init() variant to clear pktgen_threads
list.
