[Libguestfs] [PATCH common 3/4] options: Ignore errors from guestfs_luks_uuid.

[Richard W.M. Jones]

For BitLocker disks cryptsetup does not (yet? ever?) support reading
UUIDs and this function will fail.  This does not matter here so just
ignore the error.

Updates commit bb4a2dc17a78b53437896d4215ae82df8e11b788.
