remove an extra layer of buffer copying in getnameinfo reverse dns
the outer getnameinfo function already has a properly-sized temporary
buffer for storing the reverse dns (ptr) result. there is no reason
for the callback to use a secondary buffer and copy it on success, and
doing so potentially expanded the impact of the dn_expand bug that was
fixed in commit 49d2c8c6bcf8c926e52c7f510033b6adc31355f5.
this change reduces the code size by a small amount, and also reduces
the run-time stack space requirements by about 256 bytes.
