This patch fixes a bug in the driver which was
exposed by CONFIG_USB_DEBUG:
"usb 1-1.6.3: BOGUS urb flags, 40 --> 0"
The transfer flag "URB_ZERO_PACKET" is only valid
for bulk urbs.

Don't mark the device as completely dead just yet.
If all goes to plan and carl9170_reboot succeeds
then we can skip the expensive userspace-driven
reinitialization anyway.
And if it doesn't and carl9170_reboot fails,
then carl9170_usb_cancel_urbs will do the
necessary steps.

This patch prevents the tasklet code from
interfering while the firmware is down for
an unscheduled maintenance.
