dma-buf: Fix NULL pointer dereference in sanitycheck()
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")
