Andrew Cooper d69ccf52ad tools/ocaml/libs: Fix memory/resource leaks with caml_alloc_custom() ...

All caml_alloc_*() functions can throw exceptions, and longjump out of
context.  If this happens, we leak the xch/xce handle.

Reorder the logic to allocate the the Ocaml object first.

Fixes: 22d5affdf0 ("tools/ocaml/evtchn: OCaml 5 support, fix potential resource leak")
