e2freefrag: fix "Illegal block number" errors with bigalloc file systems
After:
# mke2fs -O ^has_journal,^resize_inode,^uninit_bg,extent,meta_bg,flex_bg,bigalloc /dev/sda
# e2freefrag /dev/sda
It will report error message like:
Illegal block number passed to ext2fs_test_block_bitmap #1732133 for block bitmap for /dev/sda
Illegal block number passed to ext2fs_test_block_bitmap #1732134 for block bitmap for /dev/sda
Illegal block number passed to ext2fs_test_block_bitmap #1732135 for block bitmap for /dev/sda
One bit in bitmap of bigalloc-ext4 means a cluster not a block,
therefore ext2fs_fast_test_block_bitmap2 should check cluster.
