orinoco: refactor xmit path

Browse Source 
... so orinoco_usb can share some common functionality.

Handle 802.2 encapsulation and MIC calculation in that function.
The 802.3 header is prepended to the SKB. The calculated MIC is written
to a specified buffer. Also modify the transmit control word that will
be passed onto the hardware to specify whether the MIC is present, and
the key used.
