drm/amdgpu: Fix error handling in slot reset

If the device has not recovered after slot reset is called, it goes to out label for error handling. There it could make decision based on uninitialized hive pointer and could result in accessing an uninitialized list.

Initialize the list and hive properly so that it handles the error situation and also releases the reset domain lock which is acquired during error_detected callback.
