Fedor Pchelkin 2d11505e79 dma-buf: handle testing kthreads creation failure
commit 6cb05d89fd upstream.

kthread creation may possibly fail inside race_signal_callback(). In
such a case stop the already started threads, put the already taken
references to them and return with error code.

Found by Linux Verification Center (linuxtesting.org).
