NVMe: Setup max hardware sector count to 512KB

Linux in box NVMe driver does not handle 0 MDTS as expected
•0 MDTS - the drive can accept any request size.
•The device driver set up max hardware sector size by
BLK_SAFE_MAX_SECTORS or 124KB.
•Every IO size greater than 124KB is splitted by 124KB and remainder.

Hence performance drop at 128KB IO size.
