The check is done twice indeed, which is obviously pointless. However,
I think that instead of removing the call to say_check_init_str(), we'd
better move the whole check to say.c for the sake of encapsulation, i.e.

 - rename say_check_init_str to say_check_cfg
 - pass values of 'log', 'log_format', and 'log_nonblock' to it
 - move all checks from box_check_say to say_check_cfg; after this patch
   box_check_say should only retrieve configuration options and pass
   them to say_check_cfg
