[XFRM]: Fix missing protocol comparison of larval SAs.
I noticed that in xfrm_state_add we look for the larval SA in a few places without checking for protocol match. So when using both AH and ESP, whichever one gets added first, deletes the larval SA. It seems AH always gets added first and ESP is always the larval SA's protocol since the xfrm->tmpl has it first. Thus causing the additional km_query() Adding the check eliminates accidental double SA creation. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: David S.
