octeontx2-pf: Restore TC ingress police rules when interface is up

commit 3478415166c0c392920f866561db8e1af93acbc6 from
git@git.assembla.com:cavium/WindRiver.linux.git

TC ingress policer rules depends on interface receive queue
contexts since the bandwidth profiles are attached to RQ
contexts. When an interface is brought down all the queue
contexts are freed. This in turn frees bandwidth profiles in
hardware causing ingress police rules non-functional after
the interface is brought up. Fix this by applying all the ingress
police rules config to hardware in otx2_open. Also allow
adding ingress rules only when interface is running
since no contexts exist for the interface when it is down.
