b43legacy: Fix possible NULL pointer dereference in DMA code
commit 2f9ec47d0954f9d2e5a00209c2689cbc477a8c89 upstream
This fixes a possible NULL pointer dereference in an error path of the
DMA allocation error checking code. This is also necessary for a future
DMA API change that is on its way into the mainline kernel that adds
an additional dev parameter to dma_mapping_error().
