	location of key_freesp() are wrong (you end up dereference freed
	pointer on ipseclog() because you call key_freesp() beforehand).
	other than that, those key_freesp() are needed.  thanks.

	as for key_sp_unlink(), i don't think the patch is correct.
	even if you do not call key_sp_unlink() in key_spdflush(), spd entries
	will get unlink'ed in key_timehandler().  therefore the end result
	will be the same.
