  Log:
  Invoke the driver directly when a request is submitted via crypto_dispatch
  or crypto_kdispatch unless the driver is currently blocked.  This eliminates
  the context switch to the dispatch thread for virtually all requests.
  
  Note that this change means that for software crypto drivers the caller
  will now block until the request is completed and the callback is dispatched
  to the callback thread (h/w drivers will typically just dispatch the op to
  the device and return quickly).  If this is an issue we can either implement
  a non-blocking interface in the s/w crypto driver or use either the
  "no delay" flag in the crypto request or the "software driver" capability
  flag to control what to do.
