drm/gpusvm: move dma_addr allocation before the notifier lock

The dma_addr allocation was in a lazy allocation flow, it needs unlock
and goto map_pages. The allocation only needs npages, so just do it
before taking the lock. Drop the map_pages label and the relock flow, so
the sequence becomes fault, allocate, then lock, validate, map and
unlock. No functional change intended.
