[PATCH v6 2/8] btrfs: disable verity on encrypted inodes

[Daniel Vacek <neelx@suse.com>]

From: Sweet Tea Dorminy <sweettea-kernel@dorminy.me>

Right now there isn't a way to encrypt things that aren't either
filenames in directories or data on blocks on disk with extent
encryption, so for now, disable verity usage with encryption on btrfs.
