bnxt_en: fix incorrect page count in RX aggr ring log

The warning in bnxt_alloc_one_rx_ring_netmem() reports the number
of pages allocated for the RX aggregation ring. However, it
mistakenly used bp->rx_ring_size instead of bp->rx_agg_ring_size,
leading to confusing or misleading log output.

Use the correct bp->rx_agg_ring_size value to fix this.
