eth: bnxt: fix counting packets discarded due to OOM and netpoll

I added OOM and netpoll discard counters, naively assuming that
the cpr pointer is pointing to a common completion ring.
Turns out that is usually *a* completion ring but not *the*
completion ring which bnapi->cp_ring points to. bnapi->cp_ring
is where the stats are read from, so we end up reporting 0
thru ethtool -S and qstat even though the drop events have happened.
Make 100% sure we're recording statistics in the correct structure.
