When using CQE zipping, one can choose between RX hash and Checksum.
This will indicate the parameter on which a zipping session should be
stopped.
While porting the Linux code, Checksum was chosen. However, the value
of Checksum is not being used anywhere.
For the FreeBSD driver, we prefer to use the RX hash format which will
guarantee the RX hash value for all the mini CQEs.
While at it, make sure to initialize the Checksum value in the
decompressed CQE.
