vtpm_handle_cmd doesn't ensure there is enough space before unpacking the req buffer. Add a minimum size check. Called functions will have to do their own checking if they need more data from the request. The error case is tricky since abort_egress wants to rely with a corresponding tag. Just hardcode TPM_TAG_RQU_COMMAND since the vtpm is sending in malformed commands in the first place.
