[net PATCH v2 1/2] octeontx2-af: Check whether ipolicers exists

[Rakesh Babu]

From: Subbaraya Sundeep <sbhatta@xxxxxxxxxxx>

While displaying ingress policers information in
debugfs check whether ingress policers exist in
the hardware or not because some platforms(CN9XXX)
do not have this feature.

Fixes: e7d8971763f3 ("octeontx2-af: cn10k: Debugfs support for bandwidth")
