    Allow mknod and mkfifo on SMB2/SMB3 mounts · db8b631d

    The "sfu" mount option did not work on SMB2/SMB3 mounts.
    With these changes when the "sfu" mount option is passed in
    on an smb2/smb2.1/smb3 mount the client can emulate (and
    recognize) fifo and device (character and device files).
    
    In addition the "sfu" mount option should not conflict
    with "mfsymlinks" (symlink emulation) as we will never
    create "sfu" style symlinks, but using "sfu" mount option
    will allow us to recognize existing symlinks, created with
    Microsoft "Services for Unix" (SFU and SUA).
    
    To enable the "sfu" mount option for SMB2/SMB3 the calling
    syntax of the generic cifs/smb2/smb3 sync_read and sync_write
    protocol dependent function needed to be changed (we
    don't have a file struct in all cases), but this actually
    ended up simplifying the code a little.
