Use guard() in tdx_vm_ioctl() to tidy up the code a small amount, but more importantly to minimize the diff of a future change, which will use guard-like semantics to acquire and release multiple locks. No functional change intended.
There is a tiny functional change. In the default case it no longer re-copies the struct back to userspace.
