test/rw: test reg bufs with non-align sizes/offset

Broaden registered buffers coverage with registering buffers with
non-aligned random offsets and sizes. That in particular test how we're
setting and advancing in-kernel bvecs.

Pass exp_len==-1 for that, so it compares against iov_len with which it
was initialised. Also, direct IO requires alignment, so do it in
buffered mode.
