93ffbeab77 r8152: disable the tasklet by default
Let the tasklet only be enabled after open(), and be disabled for
the other situation. The tasklet is only necessary after open() for
tx/rx, so it could be disabled by default.

d59c876dd6 r8152: stop submitting intr for -EPROTO
For Renesas USB 3.0 host controller, when unplugging the usb hub which
has the RTL8153 plugged, the driver would get -EPROTO for interrupt
transfer. There is high probability to get the information of "HC died;
cleaning up", if the driver continues to submit the interrupt transfer
before the disconnect() is called.
