[PATCH 04/14] crypto: inside-secure - remove useless check

[Antoine Tenart]

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.
