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:
  DMA-API: ps3_gelic_driver sb_05: device driver failed to check map error
  WARNING: CPU: 0 PID: 0 at kernel/dma/debug.c:1027 .check_unmap+0x888/0x8dc
