iwlwifi: handle DMA mapping failures
commit 7c34158231b2eda8dcbd297be2bb1559e69cb433 upstream.
The RX replenish code doesn't handle DMA mapping failures,
which will cause issues if there actually is a failure. This
was reported by Shuah Khan who found a DMA mapping framework
warning ("device driver failed to check map error").

[bwh: Backported to 3.2:
- Adjust filename, context, indentation
- Use bus(trans) instead of trans where necessary
- Use hw_params(trans).rx_page_order instead of trans_pcie->rx_page_order]
