features/shard: Fix block-count accounting upon truncate to lower size
Backport of:
> BUG: bz#1705884

The way delta_blocks is computed in shard is incorrect, when a file
is truncated to a lower size. The accounting only considers change
in size of the last of the truncated shards.
FIX:
Get the block-count of each shard just before an unlink at posix in
xdata. Their summation plus the change in size of last shard
(from an actual truncate) is used to compute delta_blocks which is
used in the xattrop for size update.
