crypto: skcipher - Fix request for sync algorithms 

When a sync givcipher algorithm is requested, if an async version
of the same algorithm already exists, then we will loop forever
without ever constructing the sync version based on a blkcipher.

This is because we did not include the requested type/mask when
getting a larval for the geniv algorithm that is to be constructed.
