Subject: [PATCH] net/qrtr: replaced useless kzalloc with kmalloc in qrtr_tun_write_iter()

Replaced kzalloc() with kmalloc(), there is no need for zeroed-out
memory for simple void *kbuf.

>For potential, separate clean up - this is followed 
>by copy_from_iter_full(len) kzalloc() can probably 
>be replaced by kmalloc()?
>
>>  	if (!kbuf)
>>  		return -ENOMEM;
