bnxt_en: Fix GSO type for HW GRO packets on 5750X chips

The existing code is using RSS profile to determine IPV4/IPV6 GSO type
on all chips older than 5760X.  This won't work on 5750X chips that may
be using modified RSS profiles.  This commit from 2018 has updated the
driver to not use RSS profile for HW GRO packets on newer chips:

50f011b63d8c ("bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.")

However, a recent commit to add support for the newest 5760X chip broke
the logic.  If the GRO packet needs to be re-segmented by the stack, the
wrong GSO type will cause the packet to be dropped.

Fix it to only use RSS profile to determine GSO type on the oldest
5730X/5740X chips which cannot use the new method and is safe to use the
RSS profiles.

Also fix the L3/L4 hash type for RX packets by not using the RSS
profile for the same reason.  Use the ITYPE field in the RX completion
to determine L3/L4 hash types correctly.
