[VLAN]: Clean up debugging and printks
- use pr_* functions and common prefix for non-device related messages
- remove VLAN_ printk levels
- kill lots of useless debugging statements
- remove a few unnecessary printks like for double VID registration (already
returns -EEXIST) and kill of a number of unnecessary checks in
vlan_proc_{add,rem}_dev() that are already performed by the caller
