Tim Gardner 81f53028df crypto: drbg - Fix unused value warning in drbg_healthcheck_sanity() 
Coverity warns uf an unused value:

CID 44865 (#2 of 2): Unused value (UNUSED_VALUE)
assigned_value: Assigning value -14 to ret here, but that stored value is
overwritten before it can be used.
2006        int ret = -EFAULT;
...
value_overwrite: Overwriting previous write to ret with value from drbg_seed(drbg, &addtl, false).
2052        ret = drbg_seed(drbg, &addtl, false);

Fix this by removing the variable initializer.
