Current code exit with floating point exception on a blank fs:
# btrfs-calc-size -b /dev/sda6
Calculating size of root tree
         Total size: 16384
                 Inline data: 0
         Total seeks: 0
                 Forward seeks: 0
                 Backward seeks: 0
Floating point exception

This patch add a condition check for above case.
