wifi: rtw89: mcc: refine filling function of start TSF

Browse Source 
Since tob (time offset behind) could be negative, change the type of tob in
microsecond to s32. And, refine accumulation with while-loop by calculation
with roundup_u64(). Besides, as long as one of the MCC roles is GO, use the
short MCC start time.
