Raphael S. Carvalho c729ea36e1 commitlog: guard commit log replay against reordering
After killing scylla in the middle of a write, the next scylla
instance failed to finish commit log replay, showing the following
error message:

scylla: core/future.hh:448: void promise<T>::set_value(A&& ...)
[with A = {}; T = {}]: Assertion `_state' failed.

After a long debug session, I figured out that check_valid_rp() was
triggering the exception replay_position_reordered_exception, which
means replay position reordering.

Looking at 8b9a63a3c6, I noticed that database::apply is guarded
against reodering, but commitlog replay code is not.
