No, that should work fine. You can mount the fs as many times as you
wish, and that should be without issues. If it is, that'd be a kernel
bug, and needs to be fixed there.

Note that systemd mounts efivarfs automatically to
/sys/firmware/efi/efivars anyway, so there should be no reason to ever
mount int manually?
