cifs: version operations for smb20 unneeded when legacy support disabled
We should not be including unused smb20 specific code when legacy
support is disabled (CONFIG_CIFS_ALLOW_INSECURE_LEGACY turned
off). For example smb2_operations and smb2_values aren't used
in that case. Over time we can move more and more SMB1/CIFS and SMB2.0
code into the insecure legacy ifdefs
