Mark Johnston d6dc79eabc Zero pad bytes when allocating a ZIL record ...

When allocating a record, we round up the allocation size to a multiple
of 8.  In this case, any padding bytes should be zeroed, otherwise the
contents of uninitialized memory are written to the ZIL.

This was found using KMSAN.
