wimax/i2400m: if a device reboot happens during probe, handle it
When a device reboot happens when we are under probe, with init_mutex
taken, make sure we can recover. Have dev_reset_handle set boot mode
and i2400m_msg_to_dev() will see it and fail gracefully instead of
timing out.
Found and diagnosed by Cindy H. Kao.
