Some cleanups on the loopfilter state patch.

With the bug fix in https://aomedia-review.googlesource.com/c/aom/+/52383
the encoder side workaround to get the test
AV1/AVxEncoderThreadLSTest.EncoderResultTest/* to pass is no longer
necessary.

Also removes some unnecessary lines on the decoder side.
