Theodore Ts'o 7d39db14a4 ext4: Use struct flex_groups to calculate get_orlov_stats() ...

Instead of looping over all of the block groups in a flex group
summing their summary statistics, start tracking used_dirs in struct
flex_groups, and use struct flex_groups instead.  This should save a
bit of CPU for mkdir-heavy workloads.
