smb: client: set correct file type from NFS reparse points
Handle all file types in NFS reparse points as specified in MS-FSCC
2.1.2.6 Network File System (NFS) Reparse Data Buffer.
The client is now able to set all file types based on the parsed NFS
reparse point, which used to support only symlinks. This works for
SMB1+.
Before patch:
$ mount.cifs //srv/share /mnt -o ...
$ ls -l /mnt
ls: cannot access 'block': Operation not supported
ls: cannot access 'char': Operation not supported
ls: cannot access 'fifo': Operation not supported
ls: cannot access 'sock': Operation not supported

l????????? ? ? ? ? ? char

l????????? ? ? ? ? ? fifo
l--------- 1 root root 0 Nov 18 23:23 link -> f0
l????????? ? ? ? ? ? sock
After patch:
$ mount.cifs //srv/share /mnt -o ...
$ ls -l /mnt
