crypto: sun4i-ss - initialize need_fallback

Browse Source 
commit 4ec8977b921fd9d512701e009ce8082cb94b5c1c upstream.

The need_fallback is never initialized and seem to be always true at runtime.
So all hardware operations are always bypassed.

Fixes: 0ae1f46c55 ("crypto: sun4i-ss - fallback when length is not multiple of blocksize")
