misc: vmm: streamline error Display::fmt()
The changes were mostly automatically applied using the following
Python script:
```python
import os, re
for root, _, files in os.walk("."):
for f in files:
if not f.endswith(".rs"):
continue
p = os.path.join(root, f)
with open(p, "r", encoding="utf-8") as file:
lines = file.readlines()
changed = False
for i in range(len(lines) - 1):
if re.search(r'#\[error\(".*: \{0[^}]*\}"\)\]', lines[i]) and "#[source]" in lines[i + 1].strip():
lines[i] = re.sub(r': \{0[^}]*\}"\)\]', '")]', lines[i])
changed = True
if changed:
with open(p, "w", encoding="utf-8") as file:
file.writelines(lines)
print("Fixed:", p)
```
