[PATCH] target/s390x: improve cpu compatibility check error message

[Claudio Fontana]

some users were confused by this message showing under TCG:

Selected CPU generation is too new. Maximum supported model
in the configuration: 'xyz'

Try to clarify that the maximum can depend on the accel by
adding also the current accelerator to the message as such:

Selected CPU generation is too new. Maximum supported model
in the accelerator 'tcg' configuration: 'xyz'
