[PATCH] back out netdev_priv() for loopback

Please apply this fix to backout an erroneous change in loopback.c
The statistics structure is allocated separately from the
loopback_dev structure, and the current code overwrites something
other than the statistics.  In my case the scsi_cmd_pool structure.
