Change set_encoder_config() to return void

set_encoder_config() always returns AOM_CODEC_OK, and none of the four
callers check its return value.

Also delete a block of code that was commented out when it was added in
commit 795ba876072ba38318132a8d6bc9cb2bff0c6326. If we ever want to
resurrect that block of code, it should be moved to validate_config().
