[DISKLABEL] SUN: Fix signed int usage for sector count
The current sun disklabel code uses a signed int for the sector count.
When partitions larger than 1 TB are used, the cast to a sector_t causes
the partition sizes to be invalid:
This patch switches the sector count to an unsigned int to fix this.
