[PATCH] net: mana: Fix incorrect speed reported by debugfs

[Erni Sri Satya Vennela]

Once the netshaper is created for MANA, the current bandwidth
is reported in debugfs like this:

$ sudo ./tools/net/ynl/pyynl/cli.py \
  --spec Documentation/netlink/specs/net_shaper.yaml \
  --do set \
  --json '{"ifindex":'3',
           "handle":{ "scope": "netdev", "id":'1' },
           "bw-max": 200000000 }'
None

$ sudo cat /sys/kernel/debug/mana/1/vport0/current_speed
200

After the shaper  is deleted, it is expected to report
the maximum speed supported by the SKU. But currently it is
reporting 0, which is incorrect.

Fix this inconsistency, by resetting apc->speed to apc->max_speed
during deletion of the shaper object. This will improve
readability and debuggability.
