sky2: Fix oops in sky2_xmit_frame() after TX timeout
During TX timeout procedure dev could be awoken too early, e.g. by sky2_complete_tx() called from sky2_down(). Then sky2_xmit_frame() can run while buffers are freed causing an oops. This patch fixes it by adding netif_device_present() test in sky2_tx_complete().
