dm-crypt: fully initialize clone->bi_iter in crypt_alloc_buffer()
Both kcryptd_io_read() and kcryptd_crypt_write_convert() will invoke
crypt_alloc_buffer() to allocate a new bio. Both of these two callers
initialize bi_iter.bi_sector for the new bio separatedly after
crypt_alloc_buffer() returns. However, kcryptd_crypt_write_convert()
will copy the bi_iter of the new bio into ctx.iter_out or ctx.iter_in.
Although it doesn't incur any harm now, it is better to fully initialize
bi_iter before it is used.
Therefore, initialize bi_iter.bi_sector in crypt_alloc_buffer() instead.
