The size of any bio must be aligned to the data unit size of the bio crypt
context (if it exists) of that bio. This must also be ensured whenever a
bio is split. Introduce blk_crypto_bio_sectors_alignment() that returns the
required alignment in sectors. The number of sectors passed to any call of
bio_split() must be aligned to blk_crypto_bio_sectors_alignment().
