ACPI / LPSS: Fix up acpi_lpss_create_device()

Fix a return value (which should be a negative error code) and a
memory leak (the list allocated by acpi_dev_get_resources() needs
to be freed on ioremap() errors too) in acpi_lpss_create_device()
introduced by commit 4483d59e29fe 'ACPI / LPSS: check the result
of ioremap()'.
