btrfs: use saner variable type and name to indicate extrefs at add_inode_ref()

We are using a variable named 'log_ref_ver' of type int to indicate if we
are processing an extref item or not, using a value of 1 if so, otherwise
0. This is an odd name and type, so rename it to 'is_extref_item' and
change its type to bool.
