net: fix kabi change in struct net_device_ops

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I7NDRB
CVE: NA

----------------------------------------

The member variable ndo_xdp_get_xmit_slave is added to the struct
net_device_ops in commit 879af96f("net, core: Add support for XDP
redirection to slave device"). As a result, the kabi is changed. It is
need to use the reserved KABI_RESERVE to rectify the fault.
