dbus: Fix a potential double-free in on error path (CID 62880)

Browse source 
It would have been at least theoretically possible to hit the first
error in the loop and end up jumping to error handling which would call
os_free(value) without the value having been cleared after the os_free()
call at the end of the previous loop iteration.
