buffer: calculate block number inside folio_init_buffers()
The calculation of block from index doesn't work for devices with a block
size larger than PAGE_SIZE as we end up shifting by a negative number.
Instead, calculate the number of the first block from the folio's position
in the block device. We no longer need to pass sizebits to
grow_dev_folio().
