[PATCH v2] device: fix memory leak

[Lasse Dalegaard <dalegaard@gmail.com>]

device_add_eir_uuids creates a list of added UUIDs, but it was never
freed.

This was found with LeakSanitizer from the following backtrace:

==764182==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 16 byte(s) in 1 object(s) allocated from:
