fs: btrfs: Fix not all CHUNK_ITEMs being read from CHUNK_TREE
This causes errors when translating logical addresses to physical:
btrfs_map_logical_to_physical: Cannot map logical address <addr> to physical
btrfs_file_read: Error reading extent
The behavior of btrfs_map_logical_to_physical() is to stop traversing
CHUNK_TREE when it encounters first non-CHUNK_ITEM, which makes
only some portion of CHUNK_ITEMs being read.
Change it to skip over non-chunk items.
