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.

Remove the kthread_stop_put() macro in usbip that is similar but doesn't return the result of kthread_stop().

dma-buf: fix dma-fence-chain out of order test
There was probably a misunderstand on how the dma-fence-chain is supposed to work or what dma_fence_chain_find_seqno() is supposed to return.
dma_fence_chain_find_seqno() is here to give us the fence to wait upon for a particular point in the timeline. The timeline progresses only when all the points prior to a given number have completed.
