[PATCH] sun disk label: fix signed int usage for sector count

[Jeff Mahoney <jeffm@suse.com>]

 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.
