api: remove extra useless code
api: remove extra useless code

Since the INQUIRY cmd handler is always called by tcmur_cmdproc_thread,
created by dev->handler->added(), just after rhandler->open(). And
before the thread is alive all the possible dev->max_xfer_len setting
is done. So the code here is useless.
