btrfs: move up backref sharedness cache store and lookup functions
Move the static functions to lookup and store sharedness check of an extent buffer to a location above find_all_parents(), because in the next patch the lookup function will be used by find_all_parents(). The store function is also moved just because it's the counter part to the lookup function and it's best to have their definitions close together.
