[PATCH 1/2] Fix not deleting stored keys when a new one is created

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.dentz-von@nokia.com>

When a new link key is created but it doesn't match any criteria to be
stored any previouly one should be removed from filesystem.

[PATCH 2/2] Fix not unmarking temporary flag when a new key is created

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.dentz-von@nokia.com>

Device may have been marked as temporary so when a new key is generated
and it meets the requirements to be stored the device should be no longer
temporary anymore.

I'd prefer if you just call device_set_temporary(device, temporary)
directly. That'd save you the if-check and a call to device_is_temporary.

Fair enough, I will change it and send a new patch in a few minutes.
