gfs2: Fix metadata read-ahead during truncate (2)
The previous attempt to fix for metadata read-ahead during truncate was
incorrect: for files with a height > 2 (1006989312 bytes with a block
size of 4096 bytes), read-ahead requests were not being issued for some
of the indirect blocks discovered while walking the metadata tree,
leading to significant slow-downs when deleting large files. Fix that.
In addition, only issue read-ahead requests in the first pass through
the meta-data tree, while deallocating data blocks.
