usb: gadget: f_ncm: remove check for NULL skb_tx_data in timer function

Browse source

This condition is already checked for in ncm_wrap_ntb(),
except that that check is done with eth_dev->lock held
(it is grabbed by eth_start_xmit).

It's best to not be reaching into ncm struct without locks held.
