[core] work around Windows handling of ESP for removable drives 

* Remove early locking of logical volume (no longer necessary due to previous commits).
* Relax exclusive locking of physical drive when an ESP is created.
* This should help with #1637 and #1640
* Also add an extra check for sector size in WriteDrive()
