18daae5b0c crypto: qce - Set DMA alignment explicitly 
This driver has been implicitly relying on kmalloc alignment
to be sufficient for DMA.  This may no longer be the case with
upcoming arm64 changes.

This patch changes it to explicitly request DMA alignment from
the Crypto API.

4a9dbd0219 crypto: qce - fix uaf on qce_aead_register_one 
Pointer alg points to sub field of tmpl, it
is dereferenced after tmpl is freed. Fix
this by accessing alg before free tmpl.
