Subject: [PATCH net 1/3] net: hns3: fix a use of uninitialized variable problem

From: Yonglong Liu <liuyonglong@...wei.com>

In hclge_add_fd_entry(), if the flow type is FLOW_EXT, and the data of
m_ext is all zero, then some members of the local variable "info" are
not initialized.

Fixes: 67b0e1428e2f ("net: hns3: add support for user-def data of flow director")
