[PATCH] md: allow hot-adding devices to arrays with non-persistant superblocks.
It is possibly (and occasionally useful) to have a raid1 without persistent
superblocks. The code in add_new_disk for adding a device to such an array
always tries to read a superblock.
This will obviously fail.
So do the appropriate test and call md_import_device with
appropriate args.
