crypto: inside-secure - remove useless check

Browse Source 
When sending an ahash request, the code checks for the extra variable
not to be 0. This check is useless as the extra variable can't be 0 at
this point (it is checked on the line just before).

This patch does not modify the driver behaviour in any way.
