fs: orangefs: fix error return code of orangefs_revalidate_lookup()
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.")
