Modified Files:
        src/sys/kern: subr_cprng.c

Log Message:
Fix LOCKDEBUG problems pointed out by drochner@

1) Lock ordering in cprng_strong_destroy had us take a spin mutex then
   an adaptive mutex.  Can't do that.  Reordering this requires changing
   cprng_strong_reseed to tryenter the cprng's own mutex and skip the
   reseed on failure, or we could deadlock.

2) Can't free memory with a valid mutex in it.
