[PATCH 2/6] xfs: remove iter_flags parameter from xfs_inode_walk_*

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

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.
Since there are no longer any external callers of xfs_inode_walk, make
it static.
