The raid-stripe-tree (RST) feature is for zoned devices to support extra
data profiles, and is not yet a stable feature (still requires
CONFIG_BTRFS_DEBUG enabled kernel to support it).
Furthermore the supported filesystems (ext*, reiserfs and ntfs) don't
even support zoned devices, and even we force RST support for
btrfs-convert, we would only create an empty tree for RST, as btrfs
convert would only result SINGLE data profile with SINGLE/DUP metadata
profile, neither needs RST at all.
Enabling RST for btrfs-convert would only cause problems for false test
failures as we incorrectly allow RST feature for btrfs-convert.
Fixes the problem by removing raid-stripe-tree support from
btrfs-convert and remove the test cases support for RST.
This patch is mostly reverting commit 346a381923 ("btrfs-progs:
convert: add raid-stripe-tree to allowed features"), but keeps the test
infrastructure to support bgt features for convert.
