Since commit 8a5f63637890 ("ring-buffer: Fix subbuf resize race with
ring buffer readers"), "capacity" refers to the memory available for
events, while "entries" refers to the number of events in a ring buffer.
As a consequence, rename trace_array::entries to capacity to align with
this convention.While at it, rename also tracing_total_entries_fops. It is the aggragate of all ring buffer capacities.
