[media] tm6000: remove needless check

Browse source 
Smatch reports a warning:
	drivers/media/usb/tm6000/tm6000-video.c:646 tm6000_prepare_isoc() error: we previously assumed 'dev->urb_buffer' could be null (see line 624)

This is not really a problem, but it actually shows that the check
if urb_buffer is NULL is being done twice: at the if and at
tm6000_alloc_urb_buffers().

We don't need to do it twice. So, remove the extra check. The code
become cleaner, and, as a collateral effect, smatch becomes happy.
