4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sudip Mukherjee <sudipm.mukher...@gmail.com>
commit ba60c41ae392b473a1897faa0b8739fcb8759d69 upstream.
We were taking the exit path after checking ue->flags and return value
of setup_routing_entry(), but 'e' was not freed incase of a failure.
