bspengler-oss 5946eeb8df Preserve LIFO ordering of kmap ops in abd_raidz_gen_iterate() ...

ZFS typically preserves proper LIFO ordering regarding map/unmap
operations that wrap the Linux kernel's kmap interfaces that
require such ordering, but one instance in abd_raidz_gen_iterate()
did not.

Similar issues have been fixed in the Linux kernel in the past,
see for instance CVE-2025-39899 for userfaultfd.
