Corrected an error that was causing disconnects in the hierarchical

Browse Source 
SPICE netlist output that appears to have come from flags created
for writing DEF that inappropriately got set during ext2spice.
A redundant call to efAddNodes() was adding confusion by appearing
to handle most cases but actually missing some.  With the corrected
flag, the redundant call is really redundant and can be removed.
It has not been tested whether DEF output is affected by the change
(DEF output from magic is rarely used, anyway).
