New version avoids creating a new {{.regioninfo}} only if region is a replica.

New version only avoids creating a new {{.regioninfo}} if region is a replica.

> When a RegionSever attempts to open a region, during initialization the RS
> tries to open the {{<hbase.root.dir>/data/<table>/<region>/.hregioninfo}}
> file, however if the {{.hregioninfofile}} doesn't exist, the RegionServer
> will create a new one on {{HRegionFileSystem#checkRegionInfoOnFilesystem}}. A
> side effect of that tools like hbck will incorrectly assume an inconsistency
> due the presence of this new {{.hregioninfofile}}
