tpm: fix a kernel memory leak in tpm-sysfs.c
commit 13b47cfcfc60495cde216eef4c01040d76174cbe 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.
Fixes: 0883743825e3 ("TPM: sysfs functions consolidation")
