bnxt_en: Fix allocation of zero statistics block size regression.
Recent commit added logic to determine the appropriate statistics block size to allocate and the size is stored in bp->hw_ring_stats_size. But if the firmware spec is older than 1.6.0, it is 0 and not initialized. This causes the allocation to fail with size 0 and bnxt_open() to abort. Fix it by always initializing bp->hw_ring_stats_size to the legacy default size value. Fixes: 4e748506 ("bnxt_en: Allocate the larger per-ring statistics block for 57500 chips.")
