[sheepdog] [PATCH] sheep/lib: fix coredump from dump_btree()

[Robin Dong]

From: Robin Dong <sanbai at taobao.com>

After running ./configure with "--enable-debug", the dog will coredumps when
running test case 016. The reason is that the function dump_btree() could only
be called when the type of sd_inode is B-tree.
