Avoid infinite loop for custom curves of order 1
If a private key encoded with EC parameters happens to have
order 1 and is used for ECDSA signatures, this causes an
infinite loop since a random integer x in the interval [0,1)
will be 0, so do ... while (x == 0); will loop indefinitely.
Found and reported with a reproducer by Hanno Boeck.
Helpful comments and analysis from David Benjamin.
