ata: libata-acpi: kill ata_acpi_on_suspend()
Since the commit c05e6ff035c1b25d17364a685432 ("libata-acpi: implement and use ata_acpi_init_gtm()") ata_acpi_on_suspend() just returns 0, so its call from ata_eh_handle_port_suspend() doesn't make sense anymore. Remove the function completely, at last... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
