RDMA/mlx5: Fix drop packet rule in egress table

Browse Source 
[ Upstream commit c73700806d4e430d182c2be069d230076818a99a ]

Initial drop action support missed that drop action can be added to egress
flow tables as well. Add the missing support.

This requires making sure that dest_type isn't set to PORT which in turn
exposes a possibility of passing dst while indicating number of dsts as
zero. Explicitly check for number of dsts and pass the appropriate
pointer.

Fixes: f29de9eee782 ("RDMA/mlx5: Add support for drop action in DV steering")
