Before exiting hfs_fill_super, the struct hfs_find_data used in
hfs_find_init should be passed to hfs_find_exit to be cleaned up, and
to release the lock held on the btree.
The call to hfs_find_exit is missing from an error path. We add it
back in by consolidating calls to hfs_find_exit for error paths.
