Properly handle proxmox_snap timeout parameter (#10176)

* fix: issue #10175

There is some code to handle timeout, but due to an erroneous while
test, it was never called. Use timeout >= 0 instead of timeout, so the
timeout code can be called, and properly handle timeout.

* add changelog

* Adjust changelog fragment.
