> Excess internal block can't be deleted correctly when it's stored in fallback
> storage.
> Simple case:
> EC-RS-6-3-1024k file is stored using ALL_SSD storage policy(SSD is default
> storage type and DISK is fallback storage type), if the block group is as
> follows
> [0(SSD), 0(SSD), 1(SSD), 2(SSD), 3(SSD), 4(SSD), 5(SSD), 6(SSD), 7(SSD),
> 8(DISK)]
> The are two index 0 internal block and one of them should be chosen to
> delete.But the current implement chooses the index 0 internal blocks as
> candidates but DISK as exess storage type.As a result, the exess storage
> type(DISK) can not correspond to the exess internal blocks' storage type(SSD)
> correctly, and the exess internal block can not be deleted correctly.
