pull: fix a "struct oid_array" memory leak
Fix a memory leak introduced in 44c175c7a46 (pull: error on no merge candidates, 2015-06-18). As a result we can mark several tests as passing with SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true". Removing the "int ret = 0" assignment added here in a6d7eb2c7a6 (pull: optionally rebase submodules (remote submodule changes only), 2017-06-23) is not a logic error, it could always have been left uninitialized (as "int ret"), now that we'll use the "ret" from the upper scope we can drop the assignment in the "opt_rebase" branch.
