lib: Allow hash_get to sidestep expensive hash key generation in some cases
There is no need to generate a hash key *if* the hash_alloc_function
is NULL and the hash is empty.
This changed showed a measurable increase in performance for
table hash lookup for tables that were meant to be empty in
bgp( the distance commands ).
