[PATCH AUTOSEL for 4.9 32/49] dmaengine: ioat: Fix error handling path

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 5c9afbda911ce20b3f2181d1e440a0222e1027dd ]

If the last test in 'ioat_dma_self_test()' fails, we must release all
the allocated resources and not just part of them.
