pick bug-fixes staged for 2.2.1
ZFS 2.2.1 is currently being prepared, but the 3 patches added here
seem quite relevant, as the might cause dataloss/panics on setups
which run `zpool upgrade`.
See upstreams discussion for 2.2.1:
https://github.com/openzfs/zfs/pull/15498/
and the most critical issue:
https://github.com/openzfs/zfs/pull/15529
finally:
https://github.com/openzfs/zfs/commit/
459c99ff2339a4a514abcf2255f9b3e5324ef09e
should not hurt either
the change to the UBSAN patch (0013) is unrelate, cosmetic only and
happened by running export-patchqueue.
