crypto: iaa - Fix incorrect return value in save_iaa_wq()

The save_iaa_wq() function unconditionally returns 0, even when an error
is encountered. This prevents the error code from being propagated to the
caller.

Fix this by returning the 'ret' variable, which holds the actual status
of the operations within the function.
