Christoph Hellwig 06f55fd2d2 x86/amd_gart: fix unmapping of non-GART mappings
In many cases we don't have to create a GART mapping at all, which
also means there is nothing to unmap.  Fix the range check that was
incorrectly modified when removing the mapping_error method.

Fixes: 9e8aa6b546 ("x86/amd_gart: remove the mapping_error dma_map_ops method")
