The crypto API's\ncompletion wrapper treats -EBUSY as a queueing status and swallows it,\npreventing the completion callback from firing. This causes callers\nusing crypto_wait_req() to block indefinitely.\n\nTranslate persistent -EBUSY to -EIO after retry exhaustion to ensure\nproper error propagation and callback invocation."
