QUIC: pass return code from ngx_quic_decrypt() to the caller. It is required to distinguish internal errors from corrupted packets and perform actions accordingly: drop the packet or close the connection. While there, made processing of ngx_quic_decrypt() erorrs similar and removed couple of protocol violation errors.
