The xstat by id device operation seems wrong, it fills 'xstats' struct
via 'bnxt_dev_xstats_get_op()' call, but the retrieved values are not
transferred to user input 'values' array.

ethdev layer 'rte_eth_xstats_get_by_id()' &
'rte_eth_xstats_get_names_by_id' already provides "by id" support when
device operations are missing.
It is good for PMD to provide these device operations if it has a more
performant way to get by id. But current implementation in PMD already
does same thing with the ethdev APIs, so removing them provides same
functionality.

Fixes: 88920136688c ("net/bnxt: support xstats get by id")
