Mark Johnston 03363b2f86 Initialize all fields in zfs_log_xvattr()
When logging TX_SETATTR, we could otherwise fail to initialize part of
the corresponding ZIL record depending on which fields are present in
the xvattr.  Initialize the creation time and the AV scan timestamp to
zero so that uninitialized bytes are not written to the ZIL.

This was found using KMSAN.
