[NTOSKRNL:OB]

- Actually fail when the maximum number of reparse attempts is reached in ObpLookupObjectName. It previously returned a pointer to whatever object was currently in charge of parsing, but without taking a reference to it.
- Fixes 'Header->HandleCount == 0' assertion failure (on \REGISTRY object) after running ntdll_winetest:reg three times (and also fixes the remaining test failure)
