vhost-vdpa: add reset state params to indicate reset level 

virt inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8TP8X



----------------------------------------------------------------------

When vdpa hardware is used, some hardware initialization may be
required. Currently, qemu connects to vdpa devices through the vhost
framework. Since qemu opens the vhost device, the vdpa device cannot
sense the action of qemu opening, which may cause the hardware status to
be incorrect.

Add the interface parameter state to the vdpa reset interface, which
respectively identifies the reset when the device is turned on/off
and the virtio reset issued by the virtual machine.
