[PATCH 5.10 v2 3/3] xfs: fix I_DONTCACHE

[Amir Goldstein <amir73il@gmail.com>]

From: Dave Chinner <dchinner@redhat.com>

commit f38a032b165d812b0ba8378a5cd237c0888ff65f upstream.

Yup, the VFS hoist broke it, and nobody noticed. Bulkstat workloads
make it clear that it doesn't work as it should.

Fixes: dae2f8ed7992 ("fs: Lift XFS_IDONTCACHE to the VFS layer")
