net/ps3_gelic: Fix DMA mapping problems
Fixes several DMA mapping problems with the PS3's gelic network driver:
* Change from checking the return value of dma_map_single to using the
dma_mapping_error routine.
* Use the correct buffer length when mapping the RX skb.
* Improved error checking and debug logging.
Fixes runtime errors like these, and also other randomly occurring errors:
IP-Config: Complete:
