UBIFS: make ubifs_lpt_init clean-up in case of failure
Most functions in UBIFS follow the following designn pattern: if the function allocates multiple resources, and failss at some point, it frees what it has allocated and returns an error. So the caller can rely on the fact that the callee has cleaned up everything after own failure.
