crypto: omap-des - fix crypto engine initialization order

Browse Source 
The crypto engine must be initialized before registering algorithms,
otherwise the test manager will crash as it attempts to execute
tests for the algos while they are being registered.

Fixes: f1b77aaca8 ("crypto: omap-des - Integrate with the crypto engine framework")
