net: wireless: bcmdhd: Fix driver hang when resetting
bus->tx_max was not being initialized when we do a reset and
the driver is statically linked. this led to about a 50%
chance that it would be considered an illegal value when
we send the mac address to the FW. add code to initialize
it to a safe value until we receive the right value from the fw.
