hw/tpm: Make TRACE_TPM_UTIL_SHOW_BUFFER check local to tpm_util.c
The trace_event_get_state_backends() call is useful to avoid
making extensive calls (usually preparing arguments passed to
the tracing framework. In this case, the extensive work is
done in tpm_util_show_buffer(), and the arguments used to
call it don't involve extra processing. Simplify by moving
the TRACE_TPM_UTIL_SHOW_BUFFER check to tpm_util_show_buffer.
