nui: Fix dma_mapping_error() check
[ Upstream commit 561aa0e22b70a5e7246b73d62a824b3aef3fc375 ]
dma_map_XXX() functions return values DMA_MAPPING_ERROR as error values
which is often ~0. The error value should be tested with
dma_mapping_error().
This patch creates a new function in niu_ops to test if the mapping
failed. The test is fixed in niu_rbr_add_page(), added in
niu_start_xmit() and the successfully mapped pages are unmaped upon error.
Fixes: ec2deec1f352 ("niu: Fix to check for dma mapping errors.")
