This patch isn't adding that check, it's just moving it a little earlier
in the same block.
The old code checked everything required for "MUX_GROUP" type mapping
table entries, but in the new code not all those same checks exist for
every type of mapping entry. I just moved all the common stuff to the
top of the block in one common place, followed by the stuff that varies.
So, I think that chunk is OK.
