anv/cmd_buffer: Simplify transition_depth_buffer

If we don't have HiZ, then anv_layout_to_aux_usage will return NONE for
both layouts.  If the two layouts are the same, they will get the aux
usage.  In either case, the code below will give us ISL_AUX_OP_NONE and
we'll return without doing anything.
