After DCF commits TM hierarchy configuration, the commit flag is set to
avoid duplicated commit. But the flag is not reset after device stop,
which prevents the update of hierarchy configuration unless close the
device. It is not reasonable. This patch fix to reset the commit flag
after device stop. Then users can delete and add nodes to commit a new
TM hierarchy configuration.

Fixes: 3a6bfc37eaf4 ("net/ice: support QoS config VF bandwidth in DCF")
