libsemanage: do not dereference a NULL pointer when calloc() fails

Browse Source 
If "names = calloc(num_modinfos, sizeof(*names))" fails in
semanage_get_cil_paths(), the function tries to frees items in array
"names" even though it is NULL. Avoid this by returning directly.

This issue has been found using clang's static analyzer.
