[PATCH AUTOSEL 4.18 004/100] xfrm: reset crypto_done when iterating over multiple input xfrms

[Sasha Levin]

From: Sowmini Varadhan <sowmini.varadhan@xxxxxxxxxx>

[ Upstream commit 782710e333a526780d65918d669cb96646983ba2 ]

We only support one offloaded xfrm (we do not have devices that
can handle more than one offload), so reset crypto_done in
xfrm_input() when iterating over multiple transforms in xfrm_input,
so that we can invoke the appropriate x->type->input for the
non-offloaded transforms

Fixes: d77e38e612a0 ("xfrm: Add an IPsec hardware offloading API")
