accel_engine: Fix the coredump issue if no idxd engine is found. 

The coredump info can be viewed in
https://github.com/spdk/spdk/issues/1935



We face this issue because no idxd device is attached, but we
still register the hw engine by spdk_accel_hw_engine_register
in accel_engine_idxd_init.

Fixes #1935
