The comment for SCX_KF_DISPATCH was incomplete and didn't explain that ops.dispatch() may temporarily release the rq lock, allowing ENQUEUE and SELECT_CPU operations to be nested inside DISPATCH contexts. Update the comment to clarify this nesting behavior and provide better context for when these operations can occur within dispatch.
