vfio/pci: Fix buffer overrun when writing the VF token
qemu_uuid_unparse() includes a trailing NUL when writing the uuid
string and the buffer size should be UUID_FMT_LEN + 1 bytes. Use the
recently added UUID_STR_LEN which defines the correct size.

Fixes: CID 1522913
Fixes: 2dca1b37a760 ("vfio/pci: add support for VF token")
