net/mlx5e: TC, track peer flow slots with bitmap

Browse source

With SD devices joining the LAG, peer flows are not created for all
devcom peers - SD devices skip peers that belong to a different SD
group. However, the delete path iterated all devcom peers
unconditionally, attempting to delete from slots that were never
populated.

Track which peer slots are populated using a bitmap in mlx5e_tc_flow.
The delete path now iterates only set bits, matching exactly the slots
that were set up during flow creation.
