ACPI: HMAT: Release platform device in case of platform_device_add_data() fails

The platform device is not released when platform_device_add_data()
fails. And platform_device_put() perfom one more pointer check than
put_device() to check for errors in the 'pdev' pointer.

Use platform_device_put() to release platform device in
platform_device_add()/platform_device_add_data()/
platform_device_add_resources() error case.
