Pavel Sakharov 0336995512 dma-buf: Fix NULL pointer dereference in sanitycheck() 
[ Upstream commit 2295bd846765c766701e666ed2e4b35396be25e6 ]

If due to a memory allocation failure mock_chain() returns NULL, it is
passed to dma_fence_enable_sw_signaling() resulting in NULL pointer
dereference there.

Call dma_fence_enable_sw_signaling() only if mock_chain() succeeds.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: d62c43a953ce ("dma-buf: Enable signaling on fence for selftests")
