MdeModulePkg: ScsiDiskDxe: recognize EFI_BAD_BUFFER_SIZE 

Acting specifically upon this error condition from UefiScsiLib (and
ultimately from EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru()) in the

- ScsiDiskRead10(),
- ScsiDiskWrite10(),
- ScsiDiskRead16(),
- ScsiDiskWrite16()

functions allows us to retry these operations from ScsiDiskReadSectors()
and ScsiDiskWriteSectors(), with adjusted transfer sizes, without
investigating further error details like Host Adapter Status, Target
Status, and Sense Data.
