Verify that the requested region of the mbuf chain is not beyond the end of the chain before trimming it from the end. If it is out of bounds, fail with an error (EPROTO). While here, properly handle the case that the amount of data at the end of the chain might span more than one mbuf by using m_adj to drop the extra bytes rather than assuming m_len of the last mbuf can be adjusted directly.
