The recent change to memalign() caused the allocation failure detection code to be dead code; the "retry" logic is always activated under the same condition that the original failure detection code is, and also fully handles any possible failures. This patch solves the presence of dead code.
Two alternatives are possible:
a) Delete the now-dead test, and rely on the "retry" path to handle any allocation problems, as it does.
b) Make the "retry" path fall through to the existing (currently dead) failure detection code, thus making it not-dead.
(b) was chosen since it reduces the diff between U-Boot's and the upstream dlmalloc. This should make it marginally easier to import a new version of dlmalloc in the future.

Applied to u-boot/master, thanks!
