vmstate: Mark VMStateInfo.get/put() coroutine_mixed_fn

Browse source 
Migration code can run both in coroutine context (the usual case) and
non-coroutine context (at least savevm/loadvm for snapshots). This also
affects the VMState callbacks, and devices must consider this. Change
the callback definition in VMStateInfo to be explicit about it.
