patch_parse: check if advancing over header newline succeeds

Browse Source 
While parsing patch header lines, we iterate over each line and check if
the line has trailing garbage. What we do not check though is that the
line is actually a line ending with a trailing newline.

Fix this by checking the return code of `parse_advance_expected_str`.
