pipe: fix kabi for poll_usage in struct pipe_inode_info

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6BR

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

As cd720fad8b57 ("pipe: make poll_usage boolean and annotate its access")
makes poll_usage boolean, kabi compatibility is broken for the interfaces
using struct pipo_inode_info.

Use KABI_REPLACE() to restore kabi compatibility.
