net: hns3: Fix for mailbox message truncated problem

Browse source

The payload of mailbox message is 16 byte and the value of
HCLGE_MBX_MAX_ARQ_MSG_SIZE is 8. A message truncated problem will
happen when mailbox message is converted to ARQ message. This patch
replaces HCLGE_MBX_MAX_ARQ_MSG_SIZE with the size of ARQ message in
hclgevf_mbx_handler to fix this problem.
