Masami Hiramatsu (Google) 30c8ba1da3 Revert "tracing: Add "(fault)" name injection to kernel probes" ...

[ Upstream commit 4ed8f337de ]

This reverts commit 2e9906f84f.

It was turned out that commit 2e9906f84f ("tracing: Add "(fault)"
name injection to kernel probes") did not work correctly and probe
events still show just '(fault)' (instead of '"(fault)"'). Also,
current '(fault)' is more explicit that it faulted.

This also moves FAULT_STRING macro to trace.h so that synthetic
event can keep using it, and uses it in trace_probe.c too.
