[TestFix] Remove hot and cold bricks list on regular volumes

For the non-tiered volume types, In few test cases while bringing
bricks offline, collecting both hot_tier_bricks and cold_tier_bricks
and it is not needed to collect hot and cold tier bricks.

Removing the hot and cold tiered bricks and collecting only bricks
of the particular volume as mentioned below.

Removing below section
```
bricks_to_bring_offline_dict = (select_bricks_to_bring_offline(
                self.mnode, self.volname))
bricks_to_bring_offline = list(filter(None, (
bricks_to_bring_offline_dict['hot_tier_bricks'] +
bricks_to_bring_offline_dict['cold_tier_bricks'] +
bricks_to_bring_offline_dict['volume_bricks'])))
```

Modifying as below for bringing bricks offline.
```
bricks_to_bring_offline = bricks_to_bring_offline_dict['volume_bricks']
```
