selftests/mm: drop test_uffdio_zeropage_eexist
The idea was trying to flip this var in the alarm handler from time to time to test -EEXIST of UFFDIO_ZEROPAGE, but firstly it's only used in the zeropage test so probably only used once, meanwhile we passed "retry==false" so it'll never got tested anyway. Drop both sides so we always test UFFDIO_ZEROPAGE retries if has_zeropage is set (!hugetlb). One more thing to do is doing UFFDIO_REGISTER for the alias buffer too, because otherwise the test won't even pass! We were just lucky that this test never really got ran at all.
