Subject: [PATCH] selftests/memfd: fix mfd_fail_open() to pass in buf to printf

mfd_fail_open() doesn't pass in the buffer to printf resulting
in the following warning:

memfd_test.c: In function ‘mfd_fail_open’:
memfd_test.c:208:3: warning: format ‘%s’ expects a matching ‘char *’ argument [-Wformat=]
   printf("open(%s) didn't fail as expected\n");
   ^

This change fixes the problem.
