Move the USB element out of vnt_tx_packet and vnt_beacon_xmit to vnt_tx_context with sk_buff passed in parameters with the data now between skb->data and skb->len. The vnt_tx_usb header is moved from vnt_tx_buffer to usbpipe.h with the size added to extra_tx_headroom the largest possible size. The CONTEXT enums types are aligned with usb ones and CONTEXT_MGMT_PACKET is removed and is never be used. The skb_push in vnt_tx_packet is now only ever used with vnt_get_hdr_size with variables tx_bytes and tx_header_size removed. buf_len in vnt_usb_send_context is no longer used and replaced with urb->actual_length in vnt_tx_context_complete.
