vmm: Ensure PIO/MMIO exits complete before pausing only for KVM

MSHV does not require to ensure MMIO/PIO exits complete
before pausing. This patch makes sure the above requirement
by checking the hypervisor type run-time.

Fixes #5037

build: #[allow(clippy::significant_drop_in_scrutinee) in some crates

This check is new in the beta version of clippy and exists to avoid
potential deadlocks by highlighting when the test in an if or for loop
is something that holds a lock. In many cases we would need to make
significant refactorings to be able to pass this check so disable in the
affected crates.
