YJIT: Fix incorrect exit in splat (#7575)

So by itself, this shouldn't have been a correctness issue, but we
also pop the stack for block_args. Doing stack manipulation like that
and then side-exiting causes issues. So, while this fixes the
immediate failure, we have a bigger issue with block_args popping and
then exiting that we need to deal with.
