dma-debug: Fix bug causing build warning

Stephen Rothwell reported the following build warning:

 lib/dma-debug.c: In function 'dma_debug_device_change':
 lib/dma-debug.c:680: warning: 'return' with no value, in function returning non-void

Introduced by commit f797d9881b62c2ddb1d2e7bd80d87141949c84aa
("dma-debug: Do not add notifier when dma debugging is disabled").

Return 0 [notify-done] when disabled. (this is standard bus notifier behavior.)
