btrfs-progs: check: lowmem: exclude extents of metadata blocks
Commit d17d6663c99c ("btrfs-progs: lowmem check: Fix regression which
screws up extent allocator") removes pin_metadata_blocks() from lowmem
repair. So we have to find another way to exclude extents which should
be occupied by existing tree blocks.
Modify pin_down_tree_blocks() and rename it to traverse_tree_blocks
for sharing code with new function exclude_metadata_blocks().
* exclude_metadata_blocks() traverses and marks extents of all tree
blocks dirty in fs_info->excluded_extents.
* cleanup_excluded_extents() is responsible for cleanup.
Export them to mode-common.h since they will be used both in original
and lowmem modes.
