btrfs-progs: fix floating point exception for btrfs-calc-size
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.
