crypto: arm/aes - streamline AES-192 code path

This trims off a couple of instructions of the total size of the
core AES transform by reordering the final branch in the AES-192
code path with the rounds that are performed regardless of whether
the branch is taken or not. Other than the slight size reduction,
this has no performance benefit.

Fix up a comment regarding the prototype of this function while
we're at it.
