vmm: remove duplicate vm config parameter

Vm::create_device_manager accepted both config and _vm_config, but
both represented the same VM configuration source. Remove _vm_config
from the function signature and from its call site, and use config
for the TDX dynamic check.

This is a cleanup-only refactor with no intended functional change.
