Fix check_disk free space calculation if blocksizes differ within a disk group (Bekar - #2973603)

Various values (dused_pct, dfree_pct, inodes_free, inodes_total, ...) are now carried in
the parameter_list structure. Assignments have been moved to a subroutine preventing
code redundancies.
Group metrics are now calculated based on units rather than blocks. This fixes freespace calculation
when blocksizes differ within a group.
