cifs: fix confusing unneeded warning message on smb2.1 and earlier
[ Upstream commit 53923e0fe2098f90f339510aeaa0e1413ae99a16 ]
When mounting with SMB2.1 or earlier, even with nomultichannel, we
log the confusing warning message:
"CIFS: VFS: multichannel is not supported on this protocol version, use 3.0 or above"
Fix this so that we don't log this unless they really are trying
to mount with multichannel.
