[PATCH] Keys: Fix permissions check for update vs add

Browse Source 
Permit add_key() to once again update a matching key rather than adding a
new one if a matching key already exists in the target keyring.

This bug causes add_key() to always add a new key, displacing the old from
the target keyring.
