Fix object reclaim when using large dnodes

Browse Source 
Currently, when the receive_object() code wants to reclaim an
object, it always assumes that the dnode is the legacy 512 bytes,
even when the incoming bonus buffer exceeds this length. This
causes a buffer overflow if --enable-debug is not provided and
triggers an ASSERT if it is. This patch resolves this issue and
adds an ASSERT to ensure this can't happen again.
