From: Amir Tzin <amirtz@nvidia.com>

Add "RX resources" tag to the output of rx reporter diagnose callback.
Underneath add tag for direct TIRs, for each TIR expose its tirn and
the corresponding rqtn.

$ sudo devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx
....
rx resources:
Direct TIRs:
ix: 0 tirn: 20 rqtn: 1
ix: 1 tirn: 21 rqtn: 2
ix: 2 tirn: 22 rqtn: 3
ix: 3 tirn: 23 rqtn: 4
ix: 4 tirn: 24 rqtn: 5
ix: 5 tirn: 25 rqtn: 6
