HID: Fix to show mouse pointer movements on UI

As per the UHID implementation, UHID_OPEN & UHID_CLOSE
can be ignored, but it is useful for power-management.
Since these events are handled on hid host, ready_for_data
needs to be set to TRUE. Previously the hid reports were not
sent to kernel UHID driver leading to no mouse pointer movement
on UI of DUT.
