bnxt_en: Fix HDS and jumbo thresholds for RX packets

[ Upstream commit a056ebcc ]

The recent XDP multi-buffer feature has introduced regressions in the
setting of HDS and jumbo thresholds.  HDS was accidentally disabled in
the nornmal mode without XDP.  This patch restores jumbo HDS placement
when not in XDP mode.  In XDP multi-buffer mode, HDS should be disabled
and the jumbo threshold should be set to the usable page size in the
first page buffer.
