[PATCH] rt2x00: rt2800: use tx_power2 in rt2800_config_channel_rf3xxx

[Helmut Schaa <helmut.schaa@googlemail.com>]

Get closer to what the ralink driver does by setting the rf register 13
to tx_power2 during channel switch.

Just found that difference between rt2x00 and the ralink driver.
However I couldn't see any obvious improvements. So, this change
is mostly for completeness.
