    Fix the use of uninitialized skip flag · 98fd11c5
    Jingning Han authored 
    The use of uninitialized skip flag will trigger inconsistency in
coding statistics, when alternate RD and non-RD coding modes are
enabled. This commit fixes this issue and removes unnecessary if
statements from update_state_rt.
