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.
