builtin/apply: handle parse_binary() failure
In parse_binary() there is:
forward = parse_binary_hunk(&buffer, &size, &status, &used);
if (!forward && !status)
/* there has to be one hunk (forward hunk) */
return error(_("unrecognized binary patch at line %d"), linenr-1);
so parse_binary() can return -1, because that's what error() returns.
Also parse_binary_hunk() sets "status" to -1 in case of error and
parse_binary() does "if (status) return status;".
In this case parse_chunk() should not add -1 to the patchsize it computes.
It is better for future libification efforts to make it just return -1.
