platform/x86: ishtp_eclite: Fix ACPI device reference leak in probe error path
ecl_ishtp_cl_probe() acquires a reference to an ACPI device via
acpi_find_eclite_device() but fails to release it in the error path
when acpi_opregion_init() fails. This results in a reference count
leak, preventing proper cleanup of the ACPI device.
Calling path: acpi_find_eclite_device() ->
acpi_dev_get_first_match_dev() -> acpi_dev_get_next_match_dev() ->
bus_find_device() -> get_device().
Found by code review.
