Hao Wu d7617bad96 MdeModulePkg ScsiDiskDxe: Add retry scheme for async SCSI I/O command
Some SCSI devices will return EFI_DEVICE_ERROR or EFI_TIMEOUT when the
data length of a SCSI I/O command is too large.

This commit will repeatedly retry sending the SCSI command with a data
length half of its previous value.
