ext4: fast commit may miss tracking unwritten range during ftruncate
If use FALLOC_FL_KEEP_SIZE to alloc unwritten range at bottom, the inode->i_size will not include the unwritten range. When call ftruncate with fast commit enabled, it will miss to track the unwritten range. Change to trace the full range during ftruncate.
