ata: libata-core: Disable READ LOG DMA EXT for Samsung MZ7LH
commit ead0895 upstream. Samsung MZ7LH drives are spewing messages like this in to dmesg with AMD SATA controllers: ata1.00: exception Emask 0x0 SAct 0x7e0000 SErr 0x0 action 0x6 frozen ata1.00: failed command: SEND FPDMA QUEUED ata1.00: cmd 64/01:88:00:00:00/00:00:00:00:00/a0 tag 17 ncq dma 512 out res 40/00:01:01:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) Since this was seen previously with SSD 840 EVO drives in https://bugzilla.kernel.org/show_bug.cgi?id=203475 let's add the same fix for these drives as the EVOs have, since they likely have very similar firmwares.
