### Description of PR
In HDFS-10636, the getDataInputStream method uses the
getShareDeleteFileInputStream for windows, but the getMetaDataInputStream does
not use this. The following error can happen when a DataNode is trying to
update the genstamp on a block in Windows.
DataNode Logs:
```
Caused by: java.io.IOException: Failed to rename
G:\data\hdfs\data\current\BP-1\current\finalized\subdir5\subdir16\blk_1_1.meta
to
G:\data\hdfs\data\current\BP-1\current\finalized\subdir5\subdir16\blk_1_2.meta
due to failure in native rename. 32: The process cannot access the file because
it is being used by another process.
```
