kernel: block: zero non-PI portion of auto integrity buffer

An information disclosure vulnerability was found in the Linux kernel's block layer integrity handling. When auto-generating integrity buffers for writes with protection information PI enabled, the non-PI portion of the metadata buffer is left uninitialized if the metadata size exceeds the PI tup...
