[ Upstream commit f51471d1935ce1f504fce6c115ce3bfbc32032b0 ]
According to HW spec element_type, element_attributes and parent_element_id fields
should be reserved (0x0) when calling MODIFY_SCHEDULING_ELEMENT command.
This patch remove initialization of these fields when calling the command.
Fixes: bd77bf1cb595 ("net/mlx5: Add SRIOV VF max rate configuration support")
