cifs: set rc to -ENOENT if we can not get a dentry for the cached dir

We already set rc to this return code further down in the function but
we can set it earlier in order to suppress a smash warning.

Also fix a false positive for Coverity. The reason this is a false positive is
that this happens during umount after all files and directories have been closed
but mosetting on ->on_list to suppress the warning.
