Decoder mismatch for lossless coding when RDOQ is enabled at config

[analci]

There is an encode/decode mismatch that occurs with lossless coding when RDOQ is enabled at the config level. This happens for certain frames for AI, RA and LDB configurations. An example is provided below for AI:

EncoderAppStatic -c encoder_intra_vtm.cfg -c ArenaOfValor.cfg -f 100 -ip 1 -q 0 -ts 8 -c lossless.cfg --IBC=1 --HashME=1 --DepQuant=1 --RDOQ=1 --RDOQTS=1 -b str.bin -o /dev/null -fs 0

It also appears that certain frames are being lossy coded due to this bug whereas certain frames are still lossless. A patch is provided here which prevents lossless coding from going into RDOQ for lossless. This solves the bug. A merge request will be done for this fix.
