Kawe Mazidjatari 7912b79fa2 CL_CopyExistingEntity: implement missing bounds check

Implement bounds check for non-sanitized value of u.m_nNewEntity.
Debug builds of the engine have an assertion, however in release these are stripped.
This fixes a full chain client RCE exploit, for more information, see: https://ctf.re/source-engine/exploitation/2021/05/01/source-engine-2/
