net/mlx5: Reset bw_share field when changing a node's parent

Browse source 
When changing a node's parent, its scheduling element is destroyed and
re-created with bw_share 0. However, the node's bw_share field was not
updated accordingly.

Set the node's bw_share to 0 after re-creation to keep the software
state in sync with the firmware configuration.
