    sys/vfs/hammer: Try to fix hammer_ioc_pfs_iterate() [2/2]
    
    - The ioctl HAMMERIOC_PFS_ITERATE added in commit 29d31c2d has
      several design issues. This commit and the previous try to fix
      them. Since it's been exposed to userspace, some of them are
      left as it is with comments.
    
    - Move hammer_ioc_pfs_iterate() to sys/vfs/hammer/hammer_pfs.c
      and rename it to hammer_ioc_iterate_pseudofs().
    
    - struct hammer_ioc_pfs_iterate was not necessary. The existing
      struct hammer_ioc_pseudofs_rw which is being used by all other
      pfs ioctls has everything HAMMERIOC_PFS_ITERATE needs given
      that hammer_ioc_pfs_iterate::pos is just used as a pfs id.
      Using the unique struct requires hammer_ioc_iterate_pseudofs()
      extra conversion in order to make this ioctl behave like other
      pfs ioctls using autodetect.
