Allow mknod and mkfifo on SMB2/SMB3 mounts
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.
