dma-buf: handle testing kthreads creation failure
commit 6cb05d89fd62a76a9b74bd16211fb0930e89fea8 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).
