Subject: staging: lustre: ptlrpc: kfree used instead of kvfree

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")
