can_redirect: don't treat mkdir returning EEXIST as an error
 
can_redirect's test for existance of the path followed by the mkdir
is inherently racy.  It's trivially possible to encounter a situation
where the test for existance fails in two processes and one of them
succeeds in creating the directory.  Since both processes are
looking to create and use the directory for the same purpose, we
don't need to treat EEXIST as an error.
