crypto: talitos - Avoid consecutive packets going out with same IV

The SEC's h/w IV out implementation DMAs the trailing encrypted payload
block of the last encryption to ctx->iv.  Since the last encryption may
still be pending completion, we can sufficiently prevent successive
packets from being transmitted with the same IV by xoring with sequence
number.

Also initialize alg_list earlier to prevent oopsing on a failed probe.
