4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nadav Amit namit@vmware.com
commit c3eec59659cf25916647d2178c541302bb4822ad upstream.
rq_reqbuf is allocated using kvmalloc() but released in one occasion using kfree() instead of kvfree().
The issue was found using grep based on a similar bug.
Fixes: d7e09d0397e8 ("add Lustre file system client support") Fixes: ee0ec1946ec2 ("lustre: ptlrpc: Replace uses of OBD_{ALLOC,FREE}_LARGE")
