Use correct variable for printing current opacity

Found by clang:
transSet.c:303:30: warning: variable 'opacity' is uninitialized when used here
      [-Wuninitialized]
                    (double) opacity / OPAQUE);
                             ^~~~~~~

When running transset -v, it prints the current opacity of a window
before changing it, but was printing garbage - after this fix, correctly
prints the value set by the previous run.
