tpm: tpm_spapr: Remove unused tracepoint
Linking of qemu-system-ppc64 fails on macOS with dtrace enabled: error: probe tpm_spapr_show_buffer doesn't exist error: Could not register probes ld: error creating dtrace DOF section for architecture x86_64 The failure is explained in 8c8ed03850208e4 ("net/colo: Match is-enabled probe to tracepoint"). In short, is-enabled probe can't be used without a matching trace probe. And for this particular case tpm_util_show_buffer probe should be enabled to print TPM buffer.
