Addendum to commit 5ab1cfc553.
- Static const-ify the `FloppyString` and `CdString` constants, that are
common to both `HalpNextDriveLetter()` and `xHalIoAssignDriveLetters()`.
- Improve code comments and variable names.
- In `xHalIoAssignDriveLetters()`:
* One of the two "generic string buffers" can be thrown away, since
we can already use the on-stack `Buffer`.
* No need to `sprintf` + `RtlInitAnsiString` + `RtlAnsiStringToUnicodeString`
with the risk of failing the conversion (that also allocates memory).
Instead, just invoke `swprintf` + `RtlInitUnicodeString` as already
done elsewhere in this function.
* Replace some '0' to 'FALSE' where applicable.
* Reduce indentation level of two for-loops.
