parsers: drop spurious check of readlen value

We're about to check if len < 40 after assigning readlen to len, which
means that if len < 40 we'll still abort, but I'm about to add a
sensible exception to that failure, so let's just discard this useless
check.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
