[PATCH 9/9] vmdk: make vmdk_is_cid_valid a coroutine_fn

From: Paolo Bonzini
Subject: [PATCH 9/9] vmdk: make vmdk_is_cid_valid a coroutine_fn
Date: Thu, 9 Mar 2023 09:44:56 +0100

Functions that can do I/O are prime candidates for being coroutine_fns.  Make 
change for the one that is itself called only from coroutine_fns.  Unfortunately
vmdk does not use a coroutine_fn for the bulk of the open (like qcow2 does) so
vmdk_read_cid cannot have the same treatment.
