drivers/net/pci-skeleton.c: Use (pr|netdev|netif)_<level> macro helpers 

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Remove #define PFX
Use pr_<level>
Use netdev_<level>
Use netif_<level>
Checkpatch cleaning
Convert formats like 0x%08x to %#08x
Remove periods from formats
Coalesce long formats
Use print_hex_dump
