Bluetooth: Fix UUID values in debugfs file
The uuid entry struct is used for the UUID byte stream. That is actually the wrong value. The correct value is uuid->uuid. Besides fixing this up, use the %pUb modifier to print the UUID string. However since the UUID is stored in big endian with reversed byte order, change the byte order before printing.
