Remove NOP pass statements from file.check_perms
Remove NOP pass statements from file.check_perms

While refactoring the `mode` update section the `else` statements were
removed which rendered the `if ...: pass` a NOP. The PR negates the
`if is_link and not follow_symlinks` so we only continue to change the
mode for non-links and link targets if `follow_symlinks == True`.
