Log Message:
Pull up following revision(s) (requested by chs in ticket #905):
external/cddl/osnet/dist/tools/ctf/cvt/fixup_tdescs.c: revision 1.6
Revert "Add fixup operation to remove private mutex types for x86."
The x86 (and arm) definitions of struct kmutex are no longer defined
differently depending on __MUTEX_PRIVATE.
