dmstats: fix new area count for 'create --areasize'

Browse Source 
Commit f10ad95 introduced a regression in the calculation of the
number of areas in a region created with the --areasize switch:

vg_hex-lv_home: Created new region with 0 area(s) as region ID 1
vg_hex-lv_swap: Created new region with 0 area(s) as region ID 1

Fis this by using the correct region size when calculating the
value.
