    hammer2 - Fix kmalloc pool blowout on low-memory machines
    
    * Fix a kmalloc pool blown that can occur on low-memory machines due
      to too many disconnected hammer2_inode structures building up.
    
    * Was previously fixed for things like rm -rf and bulk renames,
      but not for setattr (aka chown/chmod -R ops).
