Subject: [PATCH net-next 3/9] bnxt_en: Fix ethtool -l pre-set max combined channel.

With commit d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings."),
ring allocation for combined rings has become stricter.  A combined
ring must now have an rx-tx ring pair.  The pre-set max. for combined
rings should now be min(rx, tx).

Fixes: d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings.")
