wuzhouhui 4086464172 dif, dix: remove unnecessary _iov_iter_cont() check
Because we have called _are_iovs_valid() to ensure that all blocks are
covered by iovec, and we process iovec compactly and orderly, so we
don't need to do _iov_iter_cont() check.

Since all callee are removed, so reomve definition of _iov_iter_cont()
as well.

While here, add an assertion in _iov_iter_advance() to detect
unexpected error.
