If the DRBG is used within the scope of the FIPS OSSL_provider_init function then it attempts to register a thread callback via c_thread_start. However the implementation of c_thread_start assumed that the provider's provctx was already present. However because OSSL_provider_init is still running it was actually NULL. This means the thread callback fail to work correctly and a memory leak resulted. Instead of having c_thread_start use the provctx as the callback argument we change the definition of c_thread_start to have an explicit callback argument to use.
