  [AMDGPU] Fix broken uses of isLegalFLATOffset and splitFlatOffset (#147469)

The last parameter of these functions used to be `Signed`, and it looks
like a few calls weren't updated when that was changed to `FlatVariant`.
Effectively, the functions were called with `FlatVariant=SALU` due to
integer promotions, which doesn't make any sense.
