fscrypt: Remove fscrypt_dio_supported()
On block-based filesystems, fscrypt file contents encryption is now
always implemented using blk-crypto. This implementation supports
direct I/O.
Therefore, fscrypt_dio_supported() now always returns true, except in
the edge case where statx(STATX_DIOALIGN) is called on an encrypted
regular file that hasn't had its key set up. But that was really a
workaround rather than the desired behavior, so we can disregard it.
Thus, fscrypt_dio_supported() is no longer needed. Remove it.
