Jarkko Sakkinen 525ea5950e tpm: fix a kernel memory leak in tpm-sysfs.c ...

commit 13b47cfcfc upstream.

While cleaning up sysfs callback that prints EK we discovered a kernel
memory leak. This commit fixes the issue by zeroing the buffer used for
TPM command/response.

The leak happen when we use either tpm_vtpm_proxy, tpm_ibmvtpm or
xen-tpmfront.
