[zircon][vm][ppb] Fix (new) page replacement on ALWAYS_NEED The page replacment during ZX_VMAR_OP_ALWAYS_NEED wasn't able to unmap due to currently_faulting_ and the fact that PageFaultWithVmoCallback() expects the looked-up physical address to remain the same across vmo_locked_callback(). By not using the page fault path to set always_need = 1, we avoid currently_faulting_ true, so the unmap during ReplacePage() isn't ignored. Also fix a bad merge.
