ata: libata-core: Introduce ATA_HORKAGE_NO_LOG_DIR horkage
06f6c4c6c3e8 ("ata: libata: add missing ata_identify_page_supported() calls")
introduced additional calls to ata_identify_page_supported(), thus also
adding indirectly accesses to the device log directory log page through
ata_log_supported(). Reading this log page causes SATADOM-ML 3ME devices
to lock up.
Introduce the horkage flag ATA_HORKAGE_NO_LOG_DIR to prevent accesses to
the log directory in ata_log_supported() and add a blacklist entry
with this flag for "SATADOM-ML 3ME" devices.
Fixes: 636f6e2af4fb ("libata: add horkage for missing Identify Device log")
