ide-acpi: cleanup do_drive_set_taskfiles()
* ide_noacpi is already checked by ide_acpi_exec_tfs()
which is the only user of do_drive_set_taskfiles().
* ide_acpi_exec_tfs() prints sufficient debug info about the
device so no need to do it again.
* do_drive_get_GTF() + ide_acpi_exec_tfs() make sure that this
function will never be called with incorrect gtf_length argument
or if device is not present.
