[NETFILTER]: more verbose return codes from nf_{log,queue}

This adds EEXIST to distinguish between the following return values:
0: 	nobody was registered, registration successful
EEXIST:	the exact same handler was already registered, no registration
	required
EBUSY:	somebody else is registered, registration unsuccessful.
