Fixed bug with to-be-closed variables in base C level

To-be-closed variables in C use 'ci.nresults' to code that there is
a variable to be closed in that function. The intialization of the
base C level (the one "running" when calling API functions outside
any Lua call) did not initialize 'ci.nresults', creating (correct)
warnings in valgrind.
