[PATCH 2/2] tests/9pfs: fix coverity error in create_local_test_dir()

[Christian Schoenebeck]

Coverity wants the return value of mkdir() to be checked, so let's
pretend to do that. We're actually just making a dummy check and
ignore the result, because we actually only care if the required
directory exists and we have an existence check for that in place
already.
