merge-recursive: be consistent with assert

In commit 8daec1df03de ("merge-recursive: switch from (oid,mode) pairs to a diff_filespec", 2019-04-05), an assertion on a->path && b->path was added for code readability to document that these both needed to be non-NULL at this point in the code. However, the subsequent lines also read o->path, so it should be included in the assert. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
