[PATCH] ethdev: remove telemetry Rx mbuf alloc failed field

[PATCH] ethdev: remove telemetry Rx mbuf alloc failed field

[Ferruh Yigit]

'eth_dev->data->rx_mbuf_alloc_failed' field is not directly exposed to
user via ethdev APIs but it is used internally to set "stats->rx_nombuf'
which is exposed via ehtdev stat APIs.

But telemetry exposes this field to user via "/ethdev/info",
instead user can get 'rx_nombuf' value from stats via "/ethdev/stats".

Removing 'rx_mbuf_alloc_failed' from telemetry to align with ethdev APIs
