[PATCH hail] chunkd: don't leak an FS object iterator

[Jim Meyering <jim@meyering.net>]

chk_list_objs called fs_list_objs_open without also calling
fs_list_objs_close.

 32,808 bytes in 1 blocks are definitely lost in loss record 413 of 419

Thanks to Pete for catching my error.
To make up for that, here's a real leak fix:
