Stefan Berger c9adb76c71 tpm: vtpm_proxy: Avoid reading host log when using a virtual device 
commit 9716ac65efc8f780549b03bddf41e60c445d4709 upstream.

Avoid allocating memory and reading the host log when a virtual device
is used since this log is of no use to that driver. A virtual
device can be identified through the flag TPM_CHIP_FLAG_VIRTUAL, which
is only set for the tpm_vtpm_proxy driver.
