CVE: CVE-2024-26771

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=340049d453682a9fe8d91fe794dd091730f4bb25



--------------------------------

When devm_kcalloc fails, it forgets to call edma_free_slot.
Replace direct return with failure handler to fix it.
