VMware: prevent race for vmdk deletion

Prevent a race condition for the deletion of a file when there
is more than one process trying to erase the file.

In the application we can now handle the following specific exceptions:
 - CannotDeleteFile - the file cannot be deleted
 - FileFault - a file access exception
 - FileLocked - an attempt is made to lock a file that is
                already in use
 - FileNotFound - the specific file does not exist
