Amit Cohen 09423ff816 selftests: mlxsw: tc_police_scale: Make test more robust
commit dc97520753 upstream.

The test adds tc filters and checks how many of them were offloaded by
grepping for 'in_hw'.

iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control
action offload") added offload indication to tc actions, producing the
following output:

 $ tc filter show dev swp2 ingress
 ...
 filter protocol ipv6 pref 1000 flower chain 0 handle 0x7c0
   eth_type ipv6
   dst_ip 2001:db8:1::7bf
   skip_sw
   in_hw in_hw_count 1
         action order 1:  police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b
         ref 1 bind 1
         not_in_hw
         used_hw_stats immediate

The current grep expression matches on both 'in_hw' and 'not_in_hw',
resulting in incorrect results.

Fix that by using JSON output instead.
