Stefan Berger f0602ce389 tpm_emulator: Disconnect if response exceeds negotiated buffer size ...

Disconnect from the emulator if a response was to exceed the negotiated
buffer size.

The TPM TIS and SPAPR use 4096 bytes and the CRB 3968 bytes. There are
currently no TPM 2 responses using this size of a buffer and therefore
no response will be sent that is exceeding this size.
