cifs: Fix querying of WSL CHR and BLK reparse points over SMB1

[ Upstream commit ef86ab13 ]

When reparse point in SMB1 query_path_info() callback was detected then
query also for EA $LXDEV. In this EA are stored device major and minor
numbers used by WSL CHR and BLK reparse points. Without major and minor
numbers, stat() syscall does not work for char and block devices.

Similar code is already in SMB2+ query_path_info() callback function.
