Subject: [PATCH v2] DRBG: simplify ordering of linked list in drbg_ctr_df

This patch superseeds and replaces the initial fix submitted with [1].
After careful analysis of the code, the anticipated NULL pointer
deference is caught in drbg_ctr_update which only invokes drbg_ctr_df
when addtl is not NULL.

This patch is tested with CAVS testing and the test set provided in [2].
