ltq-deu: update initialisations for hmac algorithms

The processing in the hmac algorithms depends on the status fields:
count, dbn and started. Not all were initialised in the init method
and after finishing the final method. Added missing fields to init
method and call init method after finishing final.
The memsets have the wrong size in the original driver and did not
clear everything and are not necessary. Since no memset is done in
the kernels generic implementation, memsets were removed.
