Always allow setting number of iterations for the first time.

Browse Source 
Before this change it was impossible to set number of PKCS#5v2 iterations,
required to set passphrase, if it has two keys and never had any passphrase.
Due to present metadata format limitations there are still cases when number
of iterations can not be changed, but now it works in cases when it can.
