Fix RecursiveAlgorithms for Vitis (HAST-317)

[Piedone]

Originally opened by @DAud-IcI:

The RecursiveAlgorithms sample is broken on Viris. It doesn’t compile for U250 (possibly HBM related, see a snippet of the log with the compilation error here). It compiles for Zinq boards, but running the sample on hardware just hangs indefinitely. This has been true on the dev branch even before #35 was merged. It’s possible this sample has never been tested on Vitis, so assume the problem is not related to a recent commit.
