[PATCH 13/23] qemu: use group_name instead of QEMU_BLOCK_IOTUNE_SET_GROUP_NAME

[Nikolay Shirokovskiy]

We need qemuBlockIoTuneSetFlags to distinguish cases when some tune is not set
from tune is set explicitly to 0. We don't have the latter case for the group
name and don't need QEMU_BLOCK_IOTUNE_SET_GROUP_NAME.
