md: Use revalidate_disk to effect changes in size of device.
As revalidate_disk calls check_disk_size_change, it will cause any capacity change of a gendisk to be propagated to the blockdev inode. So use that instead of mucking about with locks and i_size_write. Also add a call to revalidate_disk in do_md_run and a few other places where the gendisk capacity is changed.
