fix: Check whether next_node is else-less if in get_return_block

Fix #124819, where a if-less block causes a wrong output. It is
caused by get_return_block in get_fn_decl. In get_return_block,
when a else-less if expression is the tail expression, the check
for next_node will keep iterating. So it is necessary to make a
early return in the check.
