Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIR

* this allows VFS implementations that prefetch stat information on
  readdir to return it through one VFS call
* backwards compatibility is maintained by passing in NULL
* if the system readdir doesn't return stat info, the stat struct is
  set to invalid
