[pbs-devel] [PATCH proxmox] async: runtime: fix `block_in_place` panicking in wrong runtime

[Max Carrara]

Because `tokio::task::block_in_place` panics if called in the
"current_thread" runtime, so does our wrapper function.

This is fixed by checking whether we're actually in a multithreaded
tokio runtime.
