Subject: xfrm: reset crypto_done when iterating over multiple
 input xfrms
Patch-mainline: v4.19-rc7
Git-commit: 782710e333a526780d65918d669cb96646983ba2
References: git-fixes


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")
