MFC r260083:

Fix extremely slow operation with data digests enabled.  This was caused
by receive code waiting for data digest even when the data segment was
empty.  It didn't actually read it, but it waited until those four bytes
become available in the socket buffer, i.e. until any other PDU (e.g. NOP)
came in.
