Since commit 9ea0dfbf972 ("dma-buf: make map_atomic and map function
pointers optional"), the core provides the no-op functions when map and
map_atomic are not provided, so we no longer need assert that are
supplied by a dma-buf exporter.

Fixes: 09ea0dfbf972 ("dma-buf: make map_atomic and map function pointers optional")
