1. [Arista] Disable SSD NCQ on Lodoga (sonic-net#13964) …

   Why I did it
   Fix similar issue seen on sonic-net#13739 but only for DCS-7050CX3-32S
   
   How I did it
   Add a kernel parameter to tell libata to disable NCQ
   
   How to verify it
   The message ata2.00: FORCE: horkage modified (noncq) should appear on the dmesg.
   
   Test results using: fio --direct=1 --rw=randrw --bs=64k --ioengine=libaio --iodepth=64 --runtime=120 --numjobs=4
   
   with NCQ
