[ Upstream commit 4c2b46c824a78fc8190d8eafaaea5a9078fe7479 ]
When op_alloc() returns NULL to new_op, no error return code of orangefs_revalidate_lookup() is assigned. To fix this bug, ret is assigned with -ENOMEM in this case.
Fixes: 8bb8aefd5afb ("OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.")
