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: 4e7485066373 ("bnxt_en: Allocate the larger per-ring statistics block for 57500 chips.")
