[ SEMANAGE ] Remove connection requirement from POLICYDB backend

This patch removes the is_connected check from the POLICYDB backend, 
because it doesn't accomplish anything. What we really want to check is 
whether the function was initialized or not (which can't be done at this 
point anyway, because we're _already_ executing this function - this is 
handled by the default database which I added).

Regarding is_connected.... we don't want to check that, because the 
POLICYDB backend will only be used in the policy server itself, which is 
exactly where we do not want a connection (server doesn't connect to 
itself). In the clients using a policy server, we're not using the 
POLICYDB backend - we're using the SERVER backend, where this parameter 
will be checked.

Besides, as is... those databases aren't even initialized if you don't 
call connect, so it's impossible to be executing that function while 
disconnected (although in the future we could initialize a database 
somewhere other than on connect).
