devlink: allow to use devlink index as a command handle
Currently devlink instances are addressed bus_name/dev_name tuple.
Allow the newly introduced DEVLINK_ATTR_INDEX to be used as
an alternative handle for all devlink commands.
When DEVLINK_ATTR_INDEX is present in the request, use it for a direct
xarray lookup instead of iterating over all instances comparing
bus_name/dev_name strings.
