block: Allow bio_iov_iter_get_pages() with bio->bi_bdev unset
bio_iov_iter_get_pages() trims the IO based on the block size of the
block device the IO will be issued to.
However, bcachefs is a multi device filesystem; when we're creating the
bio we don't yet know which block device the bio will be submitted to -
we have to handle the alignment checks elsewhere.
Thus this is needed to avoid a null ptr deref.
