crypto: sun8i-ss - fix error codes in allocate_flows()

Browse Source 
[ Upstream commit d2765e1b9a ]

These failure paths should return -ENOMEM.  Currently they return
success.

Fixes: 359e893e8a ("crypto: sun8i-ss - rework handling of IV")
Fixes: 8eec4563f1 ("crypto: sun8i-ss - do not allocate memory when handling hash requests")
