block/genhd: port disk_scan_partitions() to file
This may run from a kernel thread via device_add_disk(). So this could
also use __fput_sync() if we were worried about EBUSY. But when it is
called from a kernel thread it's always BLK_OPEN_READ so EBUSY can't
really happen even if we do BLK_OPEN_RESTRICT_WRITES or BLK_OPEN_EXCL.
Otherwise it's called from an ioctl on the block device which is only
called from userspace and can rely on task work.
