rt2x00: move extra_tx_headroom field from rt2x00_ops to rt2x00_dev
The extra_tx_headroom field of struct rt2x00_ops indicates the extra TX headroom size required for a given device. This data is redundant, the value can be computed from the desc_size and winfo_size fields of the TX queues. Move the extra_tx_headroom field to struct rt2x00_dev, compute its value in the probe routine and use the cached value in the rest of the code.
