[PATCH] btrfs-progs: misc-test: use raid1 for data to enable mount with -o degraded

[Misono, Tomohiro]

kernel 4.14 introduces new function for checking if all chunks is ok for
mount with -o degraded option.

  commit 21634a19f646 ("btrfs: Introduce a function to check if all
  chunks a OK for degraded rw mount")

As a result, raid0 profile cannot be mounted with -o degraded on 4.14.
This causes failure of the misc-test 011 "delete missing device". 

Fix this by using raid1 profile for both data and metadata.
This also should work for kernel before 4.13.
