Got it, thanks.  So it sounds to me like the only risk here is unloading
the module when witnessing is enabled.  In that case, I think the best
approach is to keep the code that reinitializes the mutex, and add
MTX_NOWITNESS to the mtx_init() flags in xa_init_flags().  Does that
seem reasonable to you?
