[Qemu-commits] [COMMIT 84e2e3e] vmstate: remove const for put operations

[Anthony Liguori]

From: Juan Quintela <address@hidden>

In a later patch, we introduce pre_save() and post_save() functions.
The whole point of that operation is to change things in the state.
Without this patch, we have to remove the const qualifier in each
use with a cast
