btrfs: use ioctl args support mask for device delete
When the device remove v2 ioctl was added, the full support mask was added to sanity check the flags. However this would allow to let the subvolume related flags to be accepted. This is not supposed to happen. Use the correct support mask, which means that now any of BTRFS_SUBVOL_CREATE_ASYNC, BTRFS_SUBVOL_RDONLY or BTRFS_SUBVOL_QGROUP_INHERIT will be rejected as ENOTSUPP. Though this is a user-visible change, specifying subvolume flags for device deletion does not make sense and there are hopefully no applications doing that.
