Btrfs-progs: fix a bug of converting sparse ext2/3/4

When converting a sparse ext* filesystem, btrfs-convert adds checksum extents
for empty extents, whose disk_bytenr = 0, and this can end up with some weird
problems, one of them is the failure of reading free space cache inode on
mounting converted btrfs.

The fix is simple, just to skip making checksum on empty extents.
