[dpdk-dev] [PATCH v4 05/29] ixgbe/base: fix firmware command checksum error

When software sends commands to firmware using the host
slave command interface, firmware fails to recieve the
request command with a checksum failed error.
This patch sets command checksum to the default value of
0xFF according to datasheet, therefore the checksum won't
be checked by firmware.
Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing on X550em_a")
Fixes: 0790adeb5675 ("ixgbe/base: support X550em_a device")
