wic: fix calculation of partition number

Total number of partitions should be taken into account when calculating
real partition number for msdos partition table. The number can be
different for the 4th partition: it can be 4 if there are 4 partitions in
the table and 5 if there are more than 4 partitions in the table. In the
latter case number 4 is occupied by extended partition.
