Details 
loptics_out() already drives lsamrot to 0 via
RtLamniController.feedback_enable_with_reset() when rtx is enabled, so the
explicit tomo_rotate(0) that followed in find_rotation_center() and
find_rotation_center_smear_experimental() was reissuing a move that had
mostly already happened -- align() already skips this same step (see its
commented-out disable/rotate/re-enable at the equivalent spot).

_tomo_rotate_if_needed() keeps the still-needed pieces: it still corrects
small residual drift from feedback briefly running before
_disable_rt_feedback(), and still performs the move when rtx is disabled
(loptics_out() then never touches lsamrot at all).
