xfs: remove iter_flags parameter from xfs_inode_walk_*

mainline-inclusion
from mainline-v5.13-rc4
commit 7fdff526
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7fdff52623b4df9c9ae665fe8bb727978c29414e

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

The sole iter_flags is XFS_INODE_WALK_INEW_WAIT, and there are no users.
Remove the flag, and the parameter, and all the code that used it.
