Btrfs: deal with errors in write_dev_supers
If you try to mount -o loop a restored file system it will panic if the file
ends up being smaller than the original disk. This is because we go to try and
get a block for a super that may be past the EOF which makes __getblk return
NULL for a buffer head when we aren't expecting it to. Fix this by dealing with
this case and just jacking up the errors count. With this patch we no longer
panic when mounting a restored file system loopback. Thanks,
