Subject: [PATCH] DO NOT MERGE. Block adoptable storage when using FBE.

For adoptable storage and FBE to coexist we need a new dm-biocrypt
kernel feature which isn't ready yet.  So for now, prevent devices
from being adopted on FBE devices.

Bug: 30770036

(cherry picked from commit 157175110948b3cf604e40420059aa5265039847)
