Remove the assumption that bv_len is a multiple of 512 bytes since this is
not guaranteed by the block layer. This assumption may cause this function
to return a smaller value than it should. This is harmless from a
correctness point of view but may result in suboptimal performance.
Note: unsigned int is sufficient for num_bytes since bio_for_each_segment()
yields at most one page per iteration and since PAGE_SIZE * BIO_MAX_VECS
fits in an unsigned int.
