Fix unloading of drivers for some platforms/medias

* Depending on the platform/media, the file system handle may have additional "phantom" disk

  that we process all the open disk protocols until we find one with a driver we can unload.

Replace potentially dodgy native file system drivers instead of attem…

…pting to use them

* Because of the AMI NTFS driver bug (https://github.com/pbatard/AmiNtfsBug) as well as
  reports of issues when using NTFS drivers different from ours, we now unconditionally
  try to unload any native file system driver that is servicing our target partition, so
  that we can replace it with one we trust.

  string, as not all drivers produce a name when using the empty string.
