block: use i_size_write() in bd_set_size()
commit d646a02a9d44d1421f273ae3923d97b47b918176 upstream.
blkdev_ioctl(GETBLKSIZE) uses i_size_read() to read size of block device.
If we update block size directly, reader may see intermediate result in
some machines and configurations. Use i_size_write() instead.
