[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: # cat /proc/paritions | grep sdan 66 112 2146435072 sdan 66 115 9223372036853660736 sdan3 66 120 9223372036853660736 sdan8 This patch switches the sector count to an unsigned int to fix this.
