Fix adding SA through netlink(xfrm_user)

Hello,

When adding IPsec SA with PF_KEY (pfkey_add()), xfrm_probe_algs() is called to make all algorithms valid. However, it is missing to call it with netlink (xfrm_user) case and it causes xfrm_aalg_get_byname() return NULL even if the name of algorithm seems to be correct.

The patch fixes it and is against 2.6.7. Please apply it.

Looks ok, but odd that this has not been picked up before.
