[ Upstream commit 117e3b7fed552eba96ae0b3b92312fe8c5b0bfdd ]
Dan Carpenter had pointed this out a while ago, but the code around this had changed so wasn't causing any problems since that field was not used in this error path.
Still, it is cleaner to always initialize this field, so changing the error path to set it.
