bpf: Fix kabi breakage in struct bpf_insn_access_aux 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYPJQ



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

After backport commit 796e26b94c7a ("bpf: Fail verification for
sign-extension of packet data/data_end/data_meta"), `is_ldsx` field was
added to the struct `bpf_insn_access_aux`, resulting in a kabi breakage.

Fix this breakage by KABI_FILL_HOLE.
