[PATCH] dma-buf: fix sanity check in dma_buf_export

[Gerd Hoffmann]

Commit 09ea0dfbf972 made map_atomic and map function pointers optional,
but didn't adapt the sanity check in dma_buf_export.  Fix that.

Note that the atomic map interface has been removed altogether meanwhile
(commit f664a52695), therefore we have to remove the map check only.
