Inside test_find_delalloc() of extent-io-tests.c, if we fail to allocate a dummy root or the test inode, we go to out label to clean up. But at that stage, @inode is still NULL and we will call process_page_range() to access the page cache of the inode, this will cause NULL pointer dereference. This is a very minor bug, as it only affects selftests which are not compiled in by default for most distros, and very hard to trigger. Fix it by adding a new out_root_info label to handle root and inode allocation failure. This is a pre-existing bug reported by Sashiko while reviewing another patch.
