When creating a dataset with ZoL a zsb->z_shares_dir ZAP object will not be created because shares are unimplemented. Instead ZoL just sets zsb->z_shares_dir to zero to indicate there are no shares. However, if you import a pool which was created with a different ZFS implementation then the shares ZAP object may exist. Code was added to handle this case but it clearly wasn't sufficiently tested with other ZFS pools. There was a bug in the zpl_shares_getattr() function which passed the wrong inode to zfs_getattr_fast() for the case where are shares ZAP object does exist. This causes an EIO to be returned to stat64() which in turn causes 'zfs diff' to fail. This fix is the pass the correct inode after a sucessful zfs_zget(). Additionally, only put away the references if we were able to get one.
