[PATCH v1] usb: xhci-dbgtty: convert tasklets to use new tasklet_setup() API

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

In preparation for unconditionally passing the struct tasklet_struct
pointer to all tasklet callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
