tmp.node was not always initialized before being used by
ebitmap_destroy.
Fixes:
Error: UNINIT (CWE-457):
libsepol-3.7/cil/src/cil_post.c:1309:2: var_decl: Declaring variable "tmp" without initializer.
libsepol-3.7/cil/src/cil_post.c:1382:6: uninit_use_in_call: Using uninitialized value "tmp.node" when calling "ebitmap_destroy".
