io_uring: fix unexpected placement on same size resizing

There might be many reasons why a user is resizing a ring, e.g. moving
to huge pages or for some memory compaction using IORING_SETUP_NO_MMAP.
Don't bypass resizing, the user will definitely be surprised seeing 0
while the rings weren't actually moved to a new place.
