qed: fix division by zero in qed_init_wfq_param when all vports are configured
In qed_init_wfq_param(), variable non_requested_count can become zero
when the number of vports with the configured flag set (including the
current vport being configured) equals total num_vports. This happens
when configuring the last unconfigured vport or when re-configuring
an already configured vport.
The function then calculates left_rate_per_vp = total_left_rate /
non_requested_count, which causes division by zero.
Fix this by skipping the division when non_requested_count is zero.
In that case, there is no remaining bandwidth to distribute, so just
record the configuration for the current vport and return success.
