fscrypt: change fscrypt_dio_supported() to prepare for STATX_DIOALIGN
To prepare for STATX_DIOALIGN support, make two changes to fscrypt_dio_supported(). First, remove the filesystem-block-alignment check and make the filesystems handle it instead. It previously made sense to have it in fs/crypto/; however, to support STATX_DIOALIGN the alignment restriction would have to be returned to filesystems. It ends up being simpler if filesystems handle this part themselves, especially for f2fs which only allows fs-block-aligned DIO in the first place. Second, make fscrypt_dio_supported() work on inodes whose encryption key hasn't been set up yet, by making it set up the key if needed. This is required for statx(), since statx() doesn't require a file descriptor.
