eth: fbnic: defer page pool recycling activation to queue start

Browse Source 
We need to be more careful about when direct page pool recycling
is enabled in preparation for queue ops support. Don't set the
NAPI pointer, call page_pool_enable_direct_recycling() from
the function that activates the queue (once the config can
no longer fail).
