If tcon is NULL there is no point in continuing in that function, we
should have exited earlier.

If tcon is NULL it means mount_get_conns() failed so presumably rc will
be != 0 and we would goto error.

I don't think this is needed. We could change the existing check after
the loop to this you really want to be safe:

	if (rc || !tcon)
		goto error;
