accel/amdxdna: Handle DETACH_DEBUG_BO through config_debug_bo path

Route DETACH_DEBUG_BO through aie2_config_debug_bo() the same way as
ATTACH_DEBUG_BO.

The scheduler switch in aie2_sched_job_run() already handles
ATTACH_DEBUG_BO with aie2_config_debug_bo(), but DETACH_DEBUG_BO was
not included in that path. Add an explicit fallthrough so both attach
and detach operations use the same handler.

This fixes debug BO detach handling by ensuring the detach command is
processed by the expected configuration path.
