eth: bnxt: make sure we populate the qcfg defaults on old FW/HW 

The driver now depends on the core to tell it what the rx page size
should be for the agg ring. We must populate the ndo_default_qcfg
callback even if we don't support any queue ops.

This fixes:
  Oops: divide error: 0000 [#1] SMP DEBUG_PAGEALLOC KASAN
  RIP: 0010:bnxt_alloc_rx_page_pool (drivers/net/ethernet/broadcom/bnxt/bnxt.c:3852)

with fw version 225.1.109.0.
