We encountered a coredump in running accel_perf with only one
ioat/idxd device enabled:
accel_perf: accel_engine.c:973: accel_engine_create_cb:
Assertion `accel_ch->engine_ch != NULL' failed.
Aborted (core dumped)
In identify_accel_engine_usage, we try to get an accel channel,
read capabilities of it, and free it. However, the hw destory_cb
is not yet called before running _init_thread because the hw destroy_cb
is delayed by accel_engine_destroy_cb, which is already a delayed
event itself. So, we simply check the first available channel's
capabilities in _init_thread to avoid such partial-free error.
