[HIFN]: Use unique driver names for different algos

    
When the CryptoAPI instantiates a new algorithm, it performs a lookup
by driver name. Since hifn uses the same name for all modes of one
algorithm, the lookup may return an incorrect algorithm.
    
Change the name to use <mode>-<algo>-<devicename> to provide unique
names for the different combinations and devices.
