Subject: [PATCH] net/mlx5: fix wire vport hint

In order to optimize number of hops in the steering tables there
was the hint field of source vport in the matcher. If this hint
was provided for the wire port the actual vport match, used by
kernel, was not set in the matcher metadata register field.
This could led to not creating the rule in hardware and E-Switch
malfunction if kernel used non-zero metadata value for the wire
vport.

This patch always sets the match for the vport metadata register
value besides the hint.
