net: ena: Change ENI stats support check to use capabilities field

Browse source

Use the capabilities field to query the device for ENI stats
support.

This replaces the previous method that tried to get the ENI stats
during ena_probe() and used the success or failure as an indication
for support by the device.

Remove eni_stats_supported field from struct ena_adapter. This field
was used for the previous method of queriying for ENI stats support.

Change the severity level of the print in case of
ena_com_get_eni_stats() failure from info to error.
With the previous method of querying form ENI stats support, failure
to get ENI stats was normal for devices that don't support it.
With the use of the capabilities field such a failure is unexpected,
as it is called only if the device reported that it supports ENI
stats.
