net: dlink: handle dma_map_single() failure properly
[ Upstream commit 65946eac6d888d50ae527c4e5c237dbe5cc3a2f2 ]
There is no error handling for `dma_map_single()` failures.
Add error handling by checking `dma_mapping_error()` and freeing
the `skb` using `dev_kfree_skb()` (process context) when it fails.
