Subject: [PATCH] vhost: mark vhost_process_iotlb_msg() static

We get 1 warning when building kernel with W=1:
drivers/vhost/vhost.c:937:5: warning: no previous prototype for 'vhost_process_iotlb_msg' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
so this patch marks this function with 'static'.
