Subject: [PATCH V2] e2fsck: fix error in computing blocks of the ending group

From: Yongqiang Yang <xiaoqiangnk@...il.com>

If the blocks of a filesystem is a multiple of blocks_per_group,
blocks of the ending group is computed wrongly.  Use the
new ext2fs_group_blocks_count() helper instead.

Eric Sandeen: Converted to use new blocks per group helper
