blender: fix build with gcc-9

GCC 9 started implementing the OpenMP 4.0 and later behavior. When not using
default clause or when using default(shared), this makes no difference, but
if using default(none), previously the choice was not specify the const
qualified variables on the construct at all, or specify in firstprivate
clause. In GCC 9 as well as for OpenMP 4.0 compliance, those variables need
to be specified on constructs in which they are used, either in shared or
in firstprivate clause. Specifying them in firstprivate clause is one way to
achieve compatibility with both older GCC versions and GCC 9,
another option is to drop the default(none) clause.

This patch thus drops the default(none) clause.

+Subject: [PATCH] Fix for GCC9 new OpenMP data sharing
+
+GCC 9 started implementing the OpenMP 4.0 and later behavior. When not using
+default clause or when using default(shared), this makes no difference, but
+if using default(none), previously the choice was not specify the const
+qualified variables on the construct at all, or specify in firstprivate
+clause. In GCC 9 as well as for OpenMP 4.0 compliance, those variables need
+to be specified on constructs in which they are used, either in shared or
+in firstprivate clause. Specifying them in firstprivate clause is one way to
+achieve compatibility with both older GCC versions and GCC 9,
+another option is to drop the default(none) clause.
+
+This patch thus drops the default(none) clause.
