[mlir] fix memory effects in GPU barrier elimination (#117432)
Existing implementation may trigger infinite cycles when collecting
effects above or below the current block after wrapping around a
loop-like construct. Limit this case to only looking at the immediate
block (loop body). This is correct because wrap around is intended to
consider effects of different iterations of the same loop and shouldn't
be existing the loop block.
