xfs: convert remaining kmem_free() to kfree()

The remaining callers of kmem_free() are freeing heap memory, so we can convert them directly to kfree() and get rid of kmem_free() altogether. This conversion was done with: $ for f in `git grep -l kmem_free fs/xfs`; do > sed -i s/kmem_free/kfree/ $f > done $ Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: "Darrick J.
