Mark Fasheh d59367262d scoutfs: remove inode mtime index ...

This index is unused - we can gain some create performance by removing it.

To verify this, I ran createmany for 10 million files:

 $ createmany -o '/scoutfs/file_%lu' 10000000

Before this patch:
 total: 10000000 creates in 776.54 seconds: 12877.56 creates/second

 real    12m56.557s
 user    0m7.861s
 sys     6m56.986s

After this patch:
 total: 10000000 creates in 691.92 seconds: 14452.46 creates/second

 real    11m31.936s
 user    0m7.785s
 sys     6m19.328s

So removing the index gained us about a minute and a half on the test or a
12% performance increase.
