random: only call crng_finalize_init() for primary_crng
commit 9d5505f upstream. crng_finalize_init() returns instantly if it is called for another pool than primary_crng. The test whether crng_finalize_init() is still required can be moved to the relevant caller in crng_reseed(), and crng_need_final_init can be reset to false if crng_finalize_init() is called with workqueues ready. Then, no previous callsite will call crng_finalize_init() unless it is needed, and we can get rid of the superfluous function parameter.
