Jason Ekstrand 0d514185ae dma-buf/sync_file: Don't leak fences on merge failure 
commit ffe000217c5068c5da07ccb1c0f8cce7ad767435 upstream.

Each add_fence() call does a dma_fence_get() on the relevant fence.  In
the error path, we weren't calling dma_fence_put() so all those fences
got leaked.  Also, in the krealloc_array failure case, we weren't
freeing the fences array.  Instead, ensure that i and fences are always
zero-initialized and dma_fence_put() all the fences and kfree(fences) on
every error path.
