only run phpcs if the file has no syntax errors.

running phpcs on a file which contains a parse error generates a huge
number of warnings from the phpcs library. This can freeze vim for
minutes at a time while it attempts to parse these
notices/warnings/errors.

Therefore - don't run phpcs on files which have parse errors.
