[Libguestfs] [PATCH v2 7/7] lib/canonical-name.c: Hide errors.

Fixes “XXX” comment.  This turns out to be necessary in order to
suppress a warning when inspecting Windows BitLocker-encrypted guests.

The warning (which still appears in debugging output even with this
patch) is:

  libguestfs: error: lvm_canonical_lv_name: /dev/mapper/cryptsda2: not a logical
volume
