[SETSEBOOL] Miscellaneous cleanups

[Ivan Gyurdiev <ivg2@cornell.edu>]

[-- Attachment #1: Type: text/plain, Size: 219 bytes --]

Remove unused ret variable causing confusion.
Simplify handling of strdup failure - the only reason strdup will fail 
is OMEM,
in which case there's no reason to go into detail regarding exactly 
which boolean failed.
