kata-types: Clean up noise caused by unformatted code

For a long time, there has been unformatted code in the kata-types
codebase, for example:
```
if qemu.memory_info.enable_guest_swap {
-                return Err(eother!(
-                    "Qemu hypervisor doesn't support enable_guest_swap"
-                ));
+                return Err(eother!("Qemu hypervisor doesn't support
enable_guest_swap"));
             }
...
-    }, device::DRIVER_NVDIMM_TYPE, eother, resolve_path
+    },
+    device::DRIVER_NVDIMM_TYPE,
+    eother, resolve_path,
-use std::collections::HashMap;
-use anyhow::{Result, anyhow};
+use anyhow::{anyhow, Result};
 use std::collections::hash_map::Entry;
+use std::collections::HashMap;
-/// DRIVER_VFIO_PCI_GK_TYPE is the device driver for vfio-pci 
+/// DRIVER_VFIO_PCI_GK_TYPE is the device driver for vfio-pci
```
This has brought unnecessary difficulties in version maintenance and
commit difficulties. This commit will address this issue.
