Fix an uninitialized data access (#16511)
zfs_acl_node_alloc allocates an uninitialized data buffer, but upstack
zfs_acl_chmod only partially initializes it.  KMSAN reported that this
memory remained uninitialized at the point when it was read by
lzjb_compress, which suggests a possible kernel memory disclosure bug.

The full KMSAN warning may be found in the PR.
