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.
