blk-crypto: use BLK_STS_INVAL for alignment errors

[ Upstream commit 0b39ca4572 ]

Make __blk_crypto_bio_prep() propagate BLK_STS_INVAL when IO segments
fail the data unit alignment check.

This was flagged by an LTP test that expects EINVAL when performing an
O_DIRECT read with a misaligned buffer [1].
