analysis: evaluate CUs when inter refinement is enabled and analysis data from
analysis save mode is unavailable.

Earlier, smaller CU sizes were evaluated only when the current block is decided
as "skip" by the save mode. This patch changes the behaviour of inter refinement
by evaluating smaller CUs irrepective of the mode of the current block.
