Allow the driver to use internal threads to
obtain fast configuration.
All the threads will be open on the same core of
the event completion queue scheduling thread.
Add max_conf_threads parameter to configure
the maximum number of internal threads in addition to
the caller thread (8 is suggested).
These internal threads to pipeline handle VDPA tasks
in system and shared with all VDPA devices.
Default is 0, don't use internal threads for configuration.
