libnm/lldp: cleanup asserting for valid NMLldpNeighbor agument

Browse Source 
At a few places we checked whether neighbor->attrs was non-NULL.
That is not necessary, unless we'd like to catch some dangling/invalid
pointers. The attrs hash is always set otherwise.

Instead of just dropping the check, add a NM_IS_LLDP_NEIGHBOR() macro
(inline function).
