[PATCH] KVM: remove printing of token address

["Tobin C. Harding" <me@tobin.cc>]

KVM currently prints the address of the consumer token. It is not
immediately clear what benefit it is to see this address. Printing
this address leaks kernel pointers into dmesg and is a security risk.

Remove the consumer token address from error message output.
