qed*: Utilize FW 8.37.2.0

This FW contains several fixes and features.

RDMA
- Several modifications and fixes for Memory Windows
- drop vlan and tcp timestamp from mss calculation in driver for
  this FW
- Fix SQ completion flow when local ack timeout is infinite
- Modifications in t10dif support

ETH
- Fix aRFS for tunneled traffic without inner IP.
- Fix chip configuration which may fail under heavy traffic conditions.
- Support receiving any-VNI in VXLAN and GENEVE RX classification.

iSCSI / FcoE
- Fix iSCSI recovery flow
- Drop vlan and tcp timestamp from mss calc for fw 8.37.2.0

Misc
- Several registers (split registers) won't read correctly with
  ethtool -d
