tpm: vtpm_proxy: Suppress error logging when in closed state 



Suppress the error logging when the core TPM driver sends commands
to the VTPM proxy driver and -EPIPE is returned in case the VTPM
proxy driver is 'closed' (closed anonymous file descriptor).  This
error code is only returned by the send function and by tpm_transmit
when the VTPM proxy driver is being used.
