WITNESS_COUNT should not need to change. If changing MAXCPU changes the
number of witness structures in use, that is a bug (it means locks are named
incorrectly). We could certainly change exhaustion of PENDLIST to not be a
panic but to disable witness instead and possibly make PENDLIST depend on
MAXCPU, but WITNESS_COUNT should not be a function of MAXCPU.
