Use kzalloc rather than the combination of kmalloc and memset.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,size,flags;
statement S;
@@
-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
if (x == NULL) S
-memset(x, 0, size);
// </smpl>

... 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.

This involves some refactorring of the common fw download code to
substitute ezusb versions of various functions.
Note that WPA-enabled firmwares (9.xx series) will not work fully with
orinoco_usb yet.

We expect to be either in process contect or soft interrupt context. So
use in_softirq instead.

This driver uses the core orinoco modules for the bulk of
the functionality. The low level hermes routines (for local bus
cards) are replaced, the driver supplies its own ndo_xmit_start
function, and locking is done with the _bh variant.
Some recent functionality is not available to the USB cards yet
(firmware loading and WPA).
Out-of-tree driver originally written by Manuel Estrada Sainz.
Thanks to Mark Davis for supplying hardware to test the updates.
