[PATCH 2/2] xfrm: fix GRO for !CONFIG_NETFILTER

[Steffen Klassert <steffen.klassert@secunet.com>]

From: Sabrina Dubroca <sd@queasysnail.net>

In xfrm_input() when called from GRO, async == 0, and we end up
skipping the processing in xfrm4_transport_finish(). GRO path will
always skip the NF_HOOK, so we don't need the special-case for
!NETFILTER during GRO processing.

Fixes: 7785bba299a8 ("esp: Add a software GRO codepath")
