description:
Remove __MUTEX_PRIVATE conditional in definition of struct kmutex.

This doesn't buy us anything but the need to hack around it in
ctfmerge to avoid massive duplication of kernel types -- which only
worked for the x86 definition.

This changes only x86 and arm for now, pending compile-testing the
remaining architectures.
