net: usb: enable the work after stop usbnet by ip down/up
Oleksij reported that:
The smsc95xx driver fails after one down/up cycle, like this:
$ nmcli device set enu1u1 managed no
$ p a a 10.10.10.1/24 dev enu1u1
$ ping -c 4 10.10.10.3
$ ip l s dev enu1u1 down
$ ip l s dev enu1u1 up
$ ping -c 4 10.10.10.3
The second ping does not reach the host. Networking also fails on other interfaces.
Enable the work by replacing the disable_work_sync() with cancel_work_sync().
[Jun Miao: completely write the commit changelog]
Fixes: 2c04d279e857 ("net: usb: Convert tasklet API to new bottom half workqueue mechanism")
