Subject: [PATCH] libsepol/cil: Use the macro NODE() whenever possible
In cil_symtab.h, the macro NODE() is defined. It refers to the first
node in the list of nodes that declare that datum. (It is rare for
a datum to have more than one node in this list.) While the macro was
used in many places, it was not used everywhere that it could be.
Change all the remaining places to use NODE().
