Eric Biggers d44ddbf417 ANDROID: revert fscrypt direct I/O support
Revert the direct I/O support for encrypted files so that we can bring
in the latest version of the patches from the mailing list.  This is
needed because in v5.5 and later, the ext4 support (via fs/iomap/) is
broken as-is -- not only is the second call to fscrypt_limit_dio_pages()
in the wrong place, but bios can exceed the intended nr_pages limit due
to multipage bvecs.  In order to fix this we need the v6 patches which
make fs/ext4/ handle the limiting instead of fs/iomap/.

On android-mainline, this fixes a failure in vts_kernel_encryption_test
(specifically, FBEPolicyTest#TestAesEmmcOptimizedPolicy) when run on a
device that uses the inlinecrypt mount option on ext4 (e.g. db845c).
