[SRU Groovy,Focal/linux-oem-5.10/Hirsute 0/2] CVE-2021-3490 fixups

[Thadeu Lima de Souza Cascardo]

We ended up applying a different fix for CVE-2021-3490. The upstream version is
less restricted on the bounds for the cases where the lower 32-bits are known.

This has been tested against reproducers for the original issue. Other tests
for different bounds have been tested as well.
