[Impact]

Due to a upstream bug blkid is unable to detect exfat partitions. This
breaks proper detection and automount of exfat formatted partitions
(e.g. SD cards or USB sticks)  in Ubuntu 14.10.

[Test Case]

Insert an exfat formatted SD Card (card is neither detected nor automounted)
or
run as root: blkid [partition]

Without the fix:
sudo blkid -p /dev/sde1
/dev/sde1: ambivalent result (probably more filesystems on the device, use wipefs(8) to see more details)

With the fix applied:
sudo blkid -p /dev/sde1
/dev/sde1: UUID="BE12-8543" VERSION="1.0" TYPE="exfat" USAGE="filesystem" PTTYPE="dos" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x7" PART_ENTRY_FLAGS="0x80" PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="32768" PART_ENTRY_SIZE="124702720" PART_ENTRY_DISK="8:64" 

[Regression Potential]

None known, the bugfix is simple and part of already released upstream
stable release (2.25.2).
