Paulo Alcantara df32e887d3 smb: client: set correct file type from NFS reparse points
[ Upstream commit 45e724022e2704b5a5193fd96f378822b0448e07 ]

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
total 1
l????????? ? ?    ?    ?            ? block
l????????? ? ?    ?    ?            ? char
-rwxr-xr-x 1 root root 5 Nov 18 23:22 f0
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
total 1

lrwxr-xr-x 1 root root          0 Nov 18 23:23 link -> f0
srwxr-xr-x 1 root root          0 Nov 19  2023 sock
