libata: fix spurious WARN_ON_ONCE() on port freeze Commit 54c38444fad6a99b4b19512f8f0055d69115e69e makes libata abort qcs after the port is frozen. This is necessary to guarantee that TF registers are accessed after the DMA engine is shutdown after an error. However, this triggers WARN_ON_ONCE() check in ata_qc_complete() spuriously. Move WARN_ON_ONCE() downwards such that failing commands while frozen doesn't trigger it.
