* In V1 of this patch, QEMU_LOCK_GUARD was placed near beginning of
the function. But that caused some unit tests to fail reporting
TIMEOUT errors. In this V2, QEMU_LOCK_GUARD is placed near
vhost_user_write() calls, to reduce the time that lock is held.

* Both (V1 & V2) compile well, but fail at '%check' stage while
running unit tests (on some machines), ie. rpm package is not built.
rpmbuild(8) on F40 machine failed, but koji scratch build with the
same SRPM worked fine. Those scratch builds are shared above. RHEL-9
SRPM built well on RHEL-9 host, but failed to build on F40 machine
reporting failure at '%check' stage of rpmbuild(8).

Thank you.
