[091/143] rt2x00: use correct headroom for transmission

[Greg KH]

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Pavel Roskin <proski@xxxxxxx>

commit b59a52f12e483b79e7d32da7ec30dcf3b2e0210b upstream.

Use rt2x00dev->ops->extra_tx_headroom, not rt2x00dev->hw->extra_tx_headroom
in the tx code, as the later may include other headroom not to be used in
the chipset driver.
