The sparse tool complains as follows:

drivers/dma-buf/dma-fence.c:249:25: warning:
 symbol 'dma_fence_lockdep_map' was not declared. Should it be static?

This variable is not used outside of dma-fence.c, so this commit
marks it static.

Fixes: 5fbff813a4a3 ("dma-fence: basic lockdep annotations")
