Subject: [PATCH 5.15 124/244] fs/ntfs3: uninitialized variable in ntfs_set_acl_ex()

From: Dan Carpenter <dan.carpenter@...cle.com>

commit d4073595d0c61463ec3a87411b19e2a90f76d3f8 upstream.

The goto out calls kfree(value) on an uninitialized pointer.  Just
return directly as the other error paths do.

Fixes: 460bbf2990b3 ("fs/ntfs3: Do not change mode if ntfs_set_ea failed")
