net/mlx5e: TX, Use correct counter in dma_map error flow

Browse source

[ Upstream commit d9a96ec362 ]

In case of a dma_mapping_error, do not use wi->num_dma
as a parameter for dma unmap function because it's yet
to be set, and holds an out-of-date value.
Use actual value (local variable num_dma) instead.

Fixes: e586b3b0ba ("net/mlx5: Ethernet Datapath files")
