[Qemu-trivial] [PATCH] tests: fix tpm-crb tpm-tis tests race

[Stefan Berger <stefanb@linux.vnet.ibm.com>]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

No need to close the TPM data socket on the emulator end, qemu will
close it after a SHUTDOWN. This avoids a race between close() and
read() in the TPM data thread.
