    sched/sched_lock: remove null pointer check of rtcb
    
    In previous commits to xiaomi, runtime null pointer checks for RTCB were 
removed.
    This could cause `sched_lock/unlock` exceptions when `DEBUG_ASSERTIONS` was 
disabled.
    In this commit, we removed all RTCB checks to improve performance by 1 
comparison cycle
