usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe()

Browse Source 
I got the following report while doing fault injection test:

  OF: ERROR: memory leak, expected refcount 1 instead of 4,
  of_node_get()/of_node_put() unbalanced - destroy cset entry:
  attach overlay node /i2c/tcpc@60/connector

If wusb3801_hw_init() fails, fwnode_handle_put() needs be called to
avoid refcount leak.

Fixes: d016cbe4d7 ("usb: typec: Support the WUSB3801 port controller")
