Subject: [PATCH] torture: remove exporting of internal functions

The functions torture_onoff_cleanup, torture_shuffle_cleanup are declared
as static and marked as EXPORT_SYMBOL. It's a bit confusing for an
internal function to be exported. The area of visibility for such function
is its .c file and all other modules. Other *.c files of the same module
can't use it, despite all other modules can. Relying on the fact that these
are the internal functions and they are not a crucial part of the API, the
patch removes the EXPORT_SYMBOL marking of the torture_onoff_cleanup and
torture_shuffle_cleanup. The patch complements commit cc47ae083026
("rcutorture: Abstract torture-test cleanup").
