Subject: [PATCH] docs: trace: fix event state structure name

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

The documentation refers to a non-existent 'struct synth_trace_state'
structure. The correct name is 'struct synth_event_trace_state'.

In other words, this patch is a mechanical substitution:
s/synth_trace_state/synth_event_trace_state/g
