ext4: support verifying data from large folios with fs-verity 



Eric Biggers already added support for verifying data from large folios
several years ago in commit 5d0f0e57 ("fsverity: support verifying
data from large folios").

With ext4 now supporting large block sizes, the fs-verity tests
`kvm-xfstests -c ext4/64k -g verity -x encrypt` pass without issues.

Therefore, remove the restriction and allow large folios to be enabled
together with fs-verity.
