rt2x00: Fix rt2500usb HW crypto: WEP 128 & AES
The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value
to indicate if the frame must be encrypted or not.
The way rt2x00_set_field32() worked it would grab the least signifcant bit
from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP
worked since they had odd-numbered values, while WEP 128 and AES were
even numbers and didn't work.
Correctly booleanize the txdecs->cipher value to allow the hardware to
encrypt the outgoing data. After this we can enable HW crypto by default again.
