Remove the resttrack attributes from the queue context held by ROCEE, and
add the resttrack attributes from the queue information maintained by the
driver.
For example:

"ifindex": 4,
"ifname": "hns_0",

In order to avoid double multiplexing of the resource when it is a CQ, add
a dedicated callback function.

Currently, the error return path when the call to function
dev->dfx->query_cqc_info fails will leak object 'context'. Fix this by
making the error return path via 'err' return return codes rather than
-EMSGSIZE, set ret appropriately for all error return paths and for the
memory leak now return via 'err' rather than just returning without
freeing context.

This patch adds support of resource track for hip08 and take dumping cq
context state used for debugging as an example. More resources track
supports for hns driver will be added in future.
The output should be as follows.
