rt2x00: Fix skbdesc->data_len initialization

skbdesc->data_len was not initialized correctly
in rt2x00pci, rt2x00usb, rt2500usb and rt73usb.

The value was set to queue->data_size which
means that the incorrect frame size was pased
to the upper layers.

Correctly base the value on either the skb->len,
or the rx frame size passed to the driver by the
device.
