Two minor bug fixes rotting in my tree:
(1) When the second malloc in yp_next fails, do not leak the memory
allocated by the first one. Same fix as yp_first.c rev. 1.9.
(2) When compiled with YPMATCHCACHE, do not fail the lookup when
reserving memory for the cache fails. Instead, just return the
correct result without caching it.
