39704e777a Set correct SELinux labels on new user directories
Make vold explicitly set the appropriate fscreate SELinux context when
creating per-user subdirectories such as /data/user/$userId.  This is
needed for these subdirectories to get the correct SELinux labels after
the sepolicy change https://r.android.com/2078213 changes their parent
directories to have different labels.

Note: the helper function being changed is also used for some other
directories, such as subdirectories of /data/misc/vold.  But this is
fine since they still get the same labels as before.

Test: see https://r.android.com/2078213

c193c3fbb8 Enforce that internal storage is prepared first
Before doing anything else in fscrypt_prepare_user_storage(), error out
if adoptable storage is being prepared before internal storage.  Without
this explicit check, making this mistake results in a sequence of weird
errors that is hard to trace back to the actual problem.
