bdev/part: Use spdk_bdev_open_ext() instead of spdk_bdev_open()

Browse Source 
This is just a drop in replacement of spdk_bdev_open().

Hold the passed remove_cb in struct spdk_bdev_part_base, and use
it in the new callback function bdev_part_base_event_cb. The resize
event is not supported for now.
