[PATCH openEuler-5.10-LTS-SP1 06/33] xfs: convert XFS_IFORK_PTR to a static inline helper

From: "Darrick J. Wong" djwong@kernel.org

mainline inclusion from mainline-v5.19-rc5 commit 732436ef916b4f338d672ea56accfdb11e8d0732 category: bugfix bugzilla: 187164, https://gitee.com/openeuler/kernel/issues/I4KIAO CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...

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

We're about to make this logic do a bit more, so convert the macro to a static inline function for better typechecking and fewer shouty macros. No functional changes here.
