Subject: [PATCH] liquidio: fix the validation of rx checksum status from NIC
 hardware

Fixed the code that was incorrectly interpreting the rx checksum validation
status from hardware, and updating kernel that the packet arrived with
correct checksum though the packet arrived with incorrect checksum and
hardware also indicated checksum is not correct.
