net/l2tp.sh: Don't try to evaluate l2tptunnel_${IFVAR} if unset
The "restructuring" commit went one step too far by combining the test for
whether l2tptunnel_${IFVAR} is defined with the test for whether the tunnel
exists, in a way that adversely affects the outer control flow. Fix it by
nesting the latter test.
