HID: intel-ish-hid: ishtp-hid-client: use helper functions for connection 

Use helper functions ishtp_cl_establish_connection() and
ishtp_cl_destroy_connection() to establish and destroy connection
respectively. These functions are used during initialization, reset and
deinitialization flows.

No functional changes are expected.
