cifs: Validate EAs for WSL reparse points

Browse source

[ Upstream commit ef201e8759 ]

Major and minor numbers for char and block devices are mandatory for stat.
So check that the WSL EA $LXDEV is present for WSL CHR and BLK reparse
points.

WSL reparse point tag determinate type of the file. But file type is
present also in the WSL EA $LXMOD. So check that both file types are same.
