[PATCH RESEND] Revert "btrfs-progs: convert: add raid-stripe-tree to allowed features"

[Qu Wenruo]

This reverts commit 346a3819237b319985ad6042d6302f67b040a803.

The RST feature (at least for now) is mostly for zoned devices to
support extra data profiles.

Thus btrfs-convert is never designed to handle RST, because there is no
way an ext4/reiserfs can even be created on a zoned device, or it would
create the correct RST tree root at all

Revert this unsupported feature to prevent false alerts.

For the record, RST first use is for zoned device but will allso fix the
raid56 problems once implemented. It can be used independently, I don't
see a reason to remove it's support from convert. Any related test
failures will be fixed separately.

*ONCE* implemented, while it's still hiding behind CONFIG_BTRFS_DEBUG.

Nope, I have already argued it again and again, only DEBUG kernel can 
even recognize the RST feature, while you still insists to enable it for 
regular mkfs.

I can not understand your eager to push such an experimental features to 
btrfs-progs meanwhile we have so many things to fix for RST.

Let me to be honest on this, I do not understand why you refuse to even 
move RST to experimental features, when no distro enables 
CONFIG_BTRFS_DEBUG by default.
Thus no 6.9 kernel can even mount a RST btrfs.

I think you're doing an immature decision on RST.

Thanks,
Qu
