[PATCH] bus: invoke TAILQ_REMOVE when bus cleanup

[Chengwen Feng <fengchengwen@huawei.com>]

Although eal_bus_cleanup() is not invoked for multiple times, this is a
good programming habit to remove the device object from list when
cleanup bus.

Fixes: 1cab1a40ea9b ("bus: cleanup devices on shutdown")
Fixes: 62b906cf06ba ("bus/uacce: introduce UACCE bus")
Fixes: 65780eada9d9 ("bus/vmbus: support cleanup")
