[PATCH 6/6] vhost-user-server: use DevicePanicNotifierFn everywhere

[Stefan Hajnoczi]

Use the DevicePanicNotifierFn typedef instead of open-coding the
function pointer. Writing the code this way avoids duplicating the
function prototype.

Also use the VuServer typedef instead of struct VuServer as required by
QEMU's coding style.
