libata-acpi: improve _GTF execution error handling and reporting
As _GTF commands can't transfer data, device error never signals
transfer error. It indicates that the device vetoed the operation, so
it's meaningless to retry.
This patch makes libata-acpi to report and continue on device errors
when executing _GTF commands. Also commands rejected by device don't
contribute to the number of _GTF commands executed.
While at it, update _GTF execution reporting such that all successful
commands are logged at KERN_DEBUG and rename taskfile_load_raw() to
ata_acpi_run_tf() for consistency.
