Qu Wenruo bd1ea5f04b btrfs: tree-checker: Enhance chunk checker to validate chunk profile
commit 80e46cf22b upstream

Btrfs-progs already have a comprehensive type checker, to ensure there
is only 0 (SINGLE profile) or 1 (DUP/RAID0/1/5/6/10) bit set for chunk
profile bits.

Do the same work for kernel.
