Dave Jiang 46a2f79455 dmaengine: idxd: move out percpu_ref_exit() to ensure it's outside submission ...

[ Upstream commit 85f604af9c ]

percpu_ref_tryget_live() is safe to call as long as ref is between init and
exit according to the function comment. Move percpu_ref_exit() so it is
called after the dma channel is no longer valid to ensure this holds true.

Fixes: 93a40a6d74 ("dmaengine: idxd: add percpu_ref to descriptor submission path")
