[fix](load data) decommission replica don't load data when it misses
versions (#38198)
BUG: when a decommission replica misses versions (last failed version >
0), it will cause a bug:
1. It cann't do compaction due to it has miss versions;
2. It cann't cloning the missing rowsets because it's decommissioned.
So if it continue to load data, its rowset will increase util it cause
error -235(TOO MANY VERSION).
Fix: don't write data to the decommission replica if it miss rowsets.
