libmtd: allow write operations when MEMWRITE is not supported
MEMWRITE is a recently introduced write interface for MTD; however, it
is only supported on NAND flash. mtd-utils should fall back to
old write methods when either ENOTTY or EOPNOTSUPP are returned.
This is a showstopper when, for instance, using ubiformat on NOR, which
don't have a mtd->write_oob interface (and thus don't support MEMWRITE):
ubiformat: formatting eraseblock 2 -- 1 % complete libmtd: error!: MEMWRITE ioctl failed for eraseblock 2 (mtd3)
error 122 (Operation not supported)
