[PATCH] btrfs-progs: for mixed group check opt before default raid profile is enforced

[Anand Jain <anand.jain@oracle.com>]

This fixes the regression introduced with the patch

    btrfs-progs: avoid write to the disk before sure to create fs

what happened with this patch is it missed the check to see if the
user has the option set before pushing the defaults.
